Best Garmin for Triathlon

Amuz Sandhu — Tue, 18 Aug 2026 20:46:28 +0000

Triathlons are grueling tests of fitness and willpower. They test your capability to run, swim and cycle – one after the other! This type of event is very demanding. Some people focus on improving one area at a time, whilst others use an overall approach. Either way, you can only know if you’re improving or not by tracking the statistics. This is where a good triathlon watch comes in. My suggestion for would be the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link].

Now some of you will notice that this suggestion is a little different to the one in our best triathlete watches article. That’s a great point though the difference between a [easyazon_link identifier=”B00O4D4KPA” locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 920XT[/easyazon_link] and the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935 model[/easyazon_link] is probably going to come down to personal preference.

Anyway, today we are going to focus on other Garmin options as well, some of which might suit you better than others depending on what your needs are. Now let’s get started and take a look through the various options!

Best Garmin for Triathlon

Best Garmin for Triathlon – Garmin Forerunner 935

A recent release from Garmin, the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] is absolutely stuffed full of useful features for triathletes. The Forerunner range is designed to be sports watches aimed at runners and triathletes specifically. The GPS capability of a Forerunner is amazing. Remember, the accuracy of location, speed, and distance all need to be on point for serious data tracking.

[easyazon_image align=”none” height=”324″ identifier=”B06XGD6CS4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/3179lQ%2BpM0L.jpg” tag=”upbeat-jan-20″ width=”500″]

Benefits

Precision GPS & Data Tracking

GPS and data tracking are better than ever on the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link]. It comes equipped with more advanced hardware, and more of it, than older Forerunners had. Features like a sensitive altimeter mean the watch can use 3D mapping accurately and provide an extremely accurate log of what distance you have covered and at what speed.

The sensors within this watch also give great readings for speed, direction, and heart rate. There’s even support for external sensors to be added, such as a heart rate strap, which boosts the accuracy even more! Compatibility with a variety of apps, such as Strava and Garmin Connect, comes as standard as well.

Great Battery Life

When it comes to battery life, you’re really going to struggle to find something more powerful than the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link]. Whilst older running watches might need charging after every use and struggle to stay working for more than a couple of uses without being recharged. Garmin claim this model can last 2 weeks without a charge in watch mode, or 24 hours in running mode. That’s already more than most people would need.

I’ve got a close friend who uses one regularly and says it’s no problem to switch to run mode for an hour or two, then back to watch mode, without needing to charge the watch until the weekend. There’s also an endurance mode available which lowers GPS accuracy but boosts battery life even further! In this mode, there have been many claims of running marathons with less than 10% battery life being lost!

[easyazon_image align=”none” height=”324″ identifier=”B06XGD6CS4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41mNJ-5MzML.jpg” tag=”upbeat-jan-20″ width=”500″]

Comfortable & Stylish

The [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] is smaller and lighter than many of the older Forerunner models, making it more comfortable to wear for prolonged periods. This also applies to the look, because the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] has a much nicer looking rounded face. Compare it to the larger, more squared face of the [easyazon_link identifier=”B00O4D4KPA” locale=”US” tag=”upbeat-jan-20″]920XT[/easyazon_link] and you’ll see what I mean. Now for many people, the [easyazon_link identifier=”B00O4D4KPA” locale=”US” tag=”upbeat-jan-20″]920XT[/easyazon_link] would be fine because they’re only looking for a training/competition watch. What I like about the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin 935[/easyazon_link] though is that it doesn’t look out of place being used day-to-day.

The rounded, thinner face lets it blend in and look perfectly normal and stylish for everyday use. With the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935[/easyazon_link], Garmin seems to have moved away from the sports-specific look which the forerunner range has always had. Instead, the look is based more on their Fenix range, which is actually designed as a watch first and sports device second, rather than the other way around. This is added to with features that monitor your body all day long,

Durable

With solid construction, silicone strap and reliable waterproof performance, this watch shouldn’t break down under regular use. Garmin is a brand known to produce reliable watches and the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] is no exception, giving the same great performance after every use.

[easyazon_image align=”none” height=”324″ identifier=”B06XGD6CS4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/3137enMjUVL.jpg” tag=”upbeat-jan-20″ width=”500″]

Drawbacks

A Little Costly

Being a newer release and the current flagship model of the Forerunner range, [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]the 935[/easyazon_link] isn’t the cheapest watch around. It actually isn’t priced much higher than other Garmin watches, though the cost could be enough to put off casual athletes. There are a lot of features on this watch which might not be important to a lot of triathletes, and if that’s the case for you, there’s probably a cheaper alternative available.

No Garmin Pay Integration

One of the bigger talking points is that this watch doesn’t support Garmin Pay, the contactless app which Garmin usually integrates in sports watches. The fact this is missing could be an inconvenience to some, especially as this is our overall top pick and many triathletes don’t like carrying anything extra, such as a phone/card/wallet. It’s still only a minor inconvenience though, so won’t knock the watch from top spot.

[easyazon_image align=”none” height=”324″ identifier=”B06XGD6CS4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31HWqrEtJYL.jpg” tag=”upbeat-jan-20″ width=”500″]

No Music Support

Music support is a bigger deal for a lot of people. Having to carry a phone while running can be a serious inconvenience and pain point. Having music functionality through a watch usually gets around this, and allows people to run using just a Bluetooth headset and their watch. That option doesn’t exist with the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link], so if you want music you’re going to need your phone. On the plus side, you can at least control the phone/music via the watch!

Best on a Budget – Garmin Forerunner 735XT

Looking to keep the cost down, or quite new to triathlons? The [easyazon_link identifier=”B01DOJDPQY” locale=”US” tag=”upbeat-jan-20″]Forerunner 735XT[/easyazon_link] could be perfect for you! It gives you plenty of data at a lower cost than the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935[/easyazon_link]. The trade-off comes on battery life and a slight issue in tracking pool laps. Neither of these should be big problems unless you’re a high level triathlete though, in which case the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935[/easyazon_link] is recommended.

[easyazon_image align=”none” height=”324″ identifier=”B01DOJDPQY” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31IucGwsjEL.jpg” tag=”upbeat-jan-20″ width=”500″]

Benefits

Versatile & Accurate Tracking

This watch offers a fast and accurate GPS for land use especially. It seems to pick up signal and position faster than even the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link], and has massive data storage capacity. Couple this with app compatibility and the ability to detect even small details, such as number of strokes while swimming, and you have plenty of data to work with when training to improve your performance.

Easy to Use

Unlike some forerunner watches, this one uses buttons rather than a touchscreen. When you’re likely to be wet, sweaty and on the move, touchscreens can be quite painful to use, so we’re glad to see that buttons are preferred on this model. Being lightweight and having a well-designed screen also adds to this usability.

[easyazon_image align=”none” height=”324″ identifier=”B01DOJDTOW” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31k0psdpjML.jpg” tag=”upbeat-jan-20″ width=”500″]

Looks & Feels Great

The lightweight and sleek design of this watch don’t only make it comfortable, it actually looks better for it too. The [easyazon_link identifier=”B01DOJDTOW” locale=”US” tag=”upbeat-jan-20″]Forerunner 735XT[/easyazon_link] wouldn’t look out of place for everyday use. There’s a choice of colors as well, so your watch can be unique and suited to your personal style. The [easyazon_link identifier=”B01DOJDPQY” locale=”US” tag=”upbeat-jan-20″]735XT[/easyazon_link] has a very comfortable silicone strap as well.

[easyazon_image align=”none” height=”323″ identifier=”B01DOJDPQY” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41Sil9qHd6L.jpg” tag=”upbeat-jan-20″ width=”500″]

Drawbacks

Poor at Tracking Certain Data (Pool Laps, Heart Rate)

Whilst the GPS unit itself is pretty good for outdoor work, [easyazon_link identifier=”B01DOJDPQY” locale=”US” tag=”upbeat-jan-20″]Garmin 735XT[/easyazon_link] relies on the accelerometer to detect when you have completed a pool length/lap. This doesn’t seem as reliable and can occasionally miss the lap/length change, messing up your data tracking. It should be obvious to see when this has occurred, and we have heard that pushing off harder and more suddenly from the sides at the start/end of a lap helps with this problem.

The heart rate monitor can be inaccurate sometimes too. This won’t be a problem for most athletes because it will still be close to the correct reading, though, at higher levels where precision is needed for training, that could pose a problem.

[easyazon_image align=”none” height=”323″ identifier=”B01DOJDTOW” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41LERGAQStL.jpg” tag=”upbeat-jan-20″ width=”500″]

Lower Battery Life

The [easyazon_link identifier=”B01DOJDTOW” locale=”US” tag=”upbeat-jan-20″]735XT[/easyazon_link] has good battery life by most fitness watch standards. It does fall short of the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935[/easyazon_link] though, with a full marathon taking around 30% of charge out of this one. That’s still plenty of battery life for most, with average users able to wear it all day, including during training, for a few days before needing to recharge. For higher level athletes though this could be a little on the low side.

[easyazon_image align=”none” height=”324″ identifier=”B01DOJDPQY” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31Y4Li24BKL.jpg” tag=”upbeat-jan-20″ width=”500″]

Best for All-Around (Daily) Use – Garmin Fenix 5

The [easyazon_link identifier=”B01NAK0DSI” locale=”US” tag=”upbeat-jan-20″]Fenix 5[/easyazon_link] is a great watch. It comes with pretty much every feature the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] has, though has a different look and is a little heavier. This heavier weight and altered look are to give it a more stylish appearance though, so it won’t look out of place in an office setting and is still functional outdoors.

[easyazon_image align=”none” height=”341″ identifier=”B01NAK0DSI” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/317iWxUmjEL.jpg” tag=”upbeat-jan-20″ width=”500″]

Benefits

Great Tracking Ability

When it comes to GPS and data tracking, the [easyazon_link identifier=”B073X35Z5M” locale=”US” tag=”upbeat-jan-20″]Fenix 5[/easyazon_link] matches any sports watch on the market today. It has all of the hardware and features to track anything you might want and have the information stored and readily available for you.

Looks Fantastic

The main reason people buy a Fenix 5 over other models is that it looks good. You can use this as an everyday watch and it doesn’t stand out as a sports watch at first glance. It uses a solid metallic build which also adds even more durability to the watch. In fact, with the scratch-proof screen on the [easyazon_link identifier=”B07171WCFB” locale=”US” tag=”upbeat-jan-20″]Fenix 5 Sapphire edition[/easyazon_link], this is more durable and dependable than the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link]. Of course, not being plastic, it looks better and more expensive too.

[easyazon_image align=”none” height=”335″ identifier=”B01NAK0DSI” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/413zrzWvz2L.jpg” tag=”upbeat-jan-20″ width=”500″]

Great Battery Life

This watch performs similarly to the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]935[/easyazon_link] for battery life, giving 24 hours of run-mode use or 2 weeks of watch-mode use. There’s also the Ultra-trac mode available, sacrificing some GPS accuracy for an even longer battery life. Battery life is more important with the [easyazon_link identifier=”B01NAK0DSI” locale=”US” tag=”upbeat-jan-20″]Fenix 5[/easyazon_link] because it isn’t marketed as a standalone sports watch, instead being pushed as an everyday watch with sports capability.

[easyazon_image align=”none” height=”344″ identifier=”B01NAK0DSI” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41m66UxUx5L.jpg” tag=”upbeat-jan-20″ width=”500″]

Drawbacks

Expensive

The price doesn’t look too bad at first glance, but for the [easyazon_link identifier=”B01NAK0DSI” locale=”US” tag=”upbeat-jan-20″]Sapphire version[/easyazon_link] (which is the most popular) it goes up quite a bit and is the most expensive of our three Garmin triathlon watches.

Smaller Yet Heavier

The face of this watch and the screen size are both smaller than similar alternatives. The heavier weight makes it 2^nd best against the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] for most triathletes, who prefer lightweight and plastic. The solid build makes it more noticeable on your wrist during sports. Having a smaller screen also limits performance a little, because features such as topographic maps aren’t available with this watch.

[easyazon_image align=”none” height=”338″ identifier=”B01NAK0DSI” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41rw%2Bp5BqCL.jpg” tag=”upbeat-jan-20″ width=”500″]

Bottom Line – Best Garmin for Triathlon

Overall, if you want to just buy one watch and wear it all the time, and cost is no issue, the [easyazon_link identifier=”B0728DR7JV” locale=”US” tag=”upbeat-jan-20″]Fenix 5 Sapphire edition[/easyazon_link] is for you.

However for those wanting a great dedicated sports watch that doesn’t need to be worn away from athletics, the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] would be my pick. Obviously the [easyazon_link identifier=”B01DOJDTOW” locale=”US” tag=”upbeat-jan-20″]Forerunner 735XT[/easyazon_link] would only be my choice if I was limited by budget or wanted to save a little money and didn’t need the extra features a [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] provides.

Best Swimming Stopwatch

Amuz Sandhu — Sat, 15 Aug 2026 23:25:56 +0000

Swimming is a hugely competitive and popular sport. In keeping with this high level of competition, tracking results, and training progress is extremely common. These stats are utilized to both track and improve performance. Of course, to do this you need a good, accurate stopwatch. The stopwatch also needs a couple of extra considerations, such as water resistance and the ability to survive being dropped on hard floors. Without these, it won’t last very long in a swimming set. Having considered those features, our top suggestion for the best swimming stopwatch would be the [easyazon_link identifier=”B005JX93H4″ locale=”US” tag=”upbeat-jan-20″]Ultrak 495 Stopwatch.[/easyazon_link]

The [easyazon_link identifier=”B005JX93H4″ locale=”US” tag=”upbeat-jan-20″]Ultrak 495[/easyazon_link] would be my absolute top pick as a stopwatch for swimming use, though there are some alternatives depending on your personal preferences. If you’re interested in any other swim equipment, why not take a look at our best swimsuits for men or best for women? Take a look below to see our run-down of the top swimming stopwatches.

Best swimming stopwatch

Best Swimming Stopwatch – Ultrak 495 Stopwatch

The [easyazon_link identifier=”B005JX93H4″ locale=”US” tag=”upbeat-jan-20″]Ultrak 495[/easyazon_link] is generally considered the top dog when it comes to swim timers. This watch is a very common sight at swim-meets and is rated very highly for its durability. Ultrak make a variety of timers with a focus on sports, including pedometers, stopwatches, and timers.

Benefits

Water-Resistant

The [easyazon_link identifier=”B005JX93H4″ locale=”US” tag=”upbeat-jan-20″]Ultrak 495[/easyazon_link] is water-resistant, an important feature for swimming. Keep in mind that water resistance is good, though it still isn’t the same as being waterproof. Imagine it dangling too far from your neck when you lean over the pool to congratulate a swimmer, or if you happen to be pulled in after a particularly big, victorious meet. Either situation could wreck your stopwatch, so if you’re using one of these, it’s best to take it off whenever it isn’t in active use.

Buttons are Easy to Hit

Easy to hit buttons are essential for a swim stopwatch. Hands might be wet or slippy, there can be condensation, and of course, there’s adrenaline and stress on top of that. Hitting the right buttons, easily and quickly, is vital. This stopwatch has large chunky buttons that accomplish exactly that.

[easyazon_image align=”center” height=”463″ identifier=”B005JX93H4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/511%2B826VxtL.jpg” tag=”upbeat-jan-20″ width=”375″]

Durable

Durability is another important feature in wet environments, especially those that tend to be made up of very hard walls and floors. Dropped watches happen sometimes, in fact, impact damage is a leading cause of overall stopwatch failures, so having one which can survive multiple high impact drops is a blessing. With the [easyazon_link identifier=”B000QU93FW” locale=”US” tag=”upbeat-jan-20″]Ultrak 495 Swimming Stopwatch[/easyazon_link] you get this benefit too. It backs this up with a generous 5-year warranty as well, covering you against most types of damage.

Backup Battery for Memory Features

Memory features are usually a matter of preference, though almost everybody would like some memory retention to be permanent. The 5-year back-up battery in this stopwatch ensures safe storage of data between battery changes, even if that’s weeks apart. This is the kind of feature which puts this watch in the top spot, especially since this and the warranty combine to give you 5 years of flawless usage at a minimum.

Detailed & Informative Display

Ultrak has created this watch to be easily viewed in a hurry. Imagine you’re tensely watching a swimmer, waiting for the precise moment they complete a lap, eyes flicking rapidly to the display to see if it might be enough, then back to the swimmer. What if the display was too small to see with that quick flick? This stopwatch has a large and clear display, which also features dual split timers incorporated on a three-row display. Easy to see even with condensation, this watch shows a variety of info at just a glance.

Choice of Colors

For those who appreciate this kind of thing, the swimming stopwatch is available in yellow or black. The choice is yours.

[easyazon_image align=”center” height=”175″ identifier=”B000QU93FW” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/21RN2vtr1mL.jpg” tag=”upbeat-jan-20″ width=”175″]

Drawbacks

More Expensive than Other Stopwatches

[easyazon_link identifier=”B005JX93H4″ locale=”US” tag=”upbeat-jan-20″]Ultraks 495 stopwatch[/easyazon_link] is a little more pricy than other vanilla stopwatches. This is balanced out a lot by the durability and warranty. You really do get what you pay for so while this might put some people off, I’d recommend it as a value over time item.

Best Budget Swimming Stopwatch – Learning Resources Simple Stopwatch

The [easyazon_link identifier=”B0035EQDTA” locale=”US” tag=”upbeat-jan-20″]Learning Resources Simple Stopwatch[/easyazon_link] is a stopwatch which stands out as being very colorful and easy to use. It was originally aimed at teachers and children. Since then it’s become known amongst other users as a good budget buy as well, and so has proven itself as a good stopwatch.

Benefits

Easy to Use

There are a couple of features that make this easy to use. Firstly, there are three easy to hit buttons, that’s all. Red is for stop, green is for go, and yellow is for clear. This is a simple system for anyone to work with, and the watch itself has a comfortable to hold rounded shape. This is topped off with a grippy, non-slip surface. Even little hands should be safe holding this in wet conditions.

[easyazon_image align=”center” height=”500″ identifier=”B0035EQDTA” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/510HAp3RYfL.jpg” tag=”upbeat-jan-20″ width=”437″]

Extremely Safe Design

The rounded design also means there are no edges or points for accidents to happen. It’s rounded, and nothing sticks out particularly far. On top of that, the battery compartment is securely shut with a small screw. If a child uses the [easyazon_link identifier=”B0035EQDTA” locale=”US” tag=”upbeat-jan-20″]Learning Resources Stopwatch[/easyazon_link], they won’t be able to access the battery and pull it out, avoiding potential choking hazards.

Bright, Colorful Appearance

The [easyazon_link identifier=”B00BQ5RH04″ locale=”US” tag=”upbeat-jan-20″]Learning Resources Simple Stopwatch[/easyazon_link] is available in three different bright, eye-catching colors. Children love the look and it really stands out, making the stopwatch tough to lose or leave laying around.

Cheap

The price for one of these stopwatches is below that of any advanced stopwatch. This makes it a cheap investment, especially for those unsure how much use they’ll actually get from a stopwatch.

Large Display

The display is large on this stopwatch too. [easyazon_link identifier=”B0035EQDTA” locale=”US” tag=”upbeat-jan-20″]Learning Resources Stopwatch[/easyazon_link] has a big, clear display as the focus is on being clear to read.

[easyazon_image align=”center” height=”500″ identifier=”B00BQ5RH04″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41aAZKDUeWL.jpg” tag=”upbeat-jan-20″ width=”391″]

Drawbacks

Lacks Advanced Features

This isn’t the type of stopwatch which features a bunch of split timers or memory features. It’s a basic stopwatch and good as a beginning tool. Those who find a serious need for good stopwatch functions should definitely be looking to invest in an upgrade.

Limited Display

The display is basic and remains on at all times. Battery draw is low so the longevity is still high. With that said, the display is only the current time. You can stop, go, or reset. That’s all. If you need more than that, you should also be looking at something more capable than the [easyazon_link identifier=”B0035EQDTA” locale=”US” tag=”upbeat-jan-20″]Learning Resources Stopwatch[/easyazon_link].

Best Swimming Stopwatch: Garmin Forerunner 935 – Best Watch Style Stopwatch

The [easyazon_link identifier=”B0744PQMSZ” locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link] is definitely a step up in terms of investment, though it’s so much more than just a swimming stopwatch. This is an all-around watch with incredible data tracking capabilities in water and on land. It’s dependable, stuffed full of advanced features, and looks great too. The advantage of this device is that you can use it whilst swimming, as it’s always on your wrist. For other swimming watches, take a look at our best watches for triathletes article.

Benefits

Has Swim Specific Tracking Features

There are a great number of pool features on this watch. For starters, there’s the obvious stopwatch. This is a fairly basic stopwatch, giving lap times and not much else, though this is enough for some users. The [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin 935[/easyazon_link] also has a stroke detector and lap detector, which work automatically so you don’t have to mess with buttons whilst swimming. There have been some questions about the accuracy of these features though. GPS features allow you to track outdoor swim distances, while there’s a buzz alert feature which you can set up to go off after certain amounts of time or distance.

[easyazon_image align=”center” height=”324″ identifier=”B06XGD6CS4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/3179lQ%2BpM0L.jpg” tag=”upbeat-jan-20″ width=”500″]

Comes With Many Extra Features

On top of the swimming features, the GPS works for all other situations too. There are also downloadable workouts, phone connectivity, and a heart monitor. Combined with high battery life, this becomes a very versatile watch/tracker. It also has an altimeter, a barometer, and an electronic compass built-in.

Waterproof

This watch is completely waterproof, with a rating of 5ATM which is roughly equivalent to 50 meters depth. That’s far more than any swimmer is going to need, in fact without diving equipment you’re never going to get close to that depth.

Reliable

As with most Garmin devices, the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″] Forerunner 935 [/easyazon_link] is known for reliability. It can take bumps, bangs, and drops without missing a step. This and being waterproof mean it should last for a long time even with daily use.

App Allows Advanced Tracking

Phone connectivity gives the ability to use Garmins app and get extra workouts, and data tracking capability. The amount of data this watch gives is pretty high too, so while the stopwatch feature is a little basic, the overall info level is pretty high.

Fitness Performance Data

Garmin has created this watch with performance technology that can track your performance and work rate. This features auto-stroke detection for swimming and also tracks changes in your heart rate to let you know whether you’re maxing out your potential or not.

[easyazon_image align=”center” height=”500″ identifier=”B073WMPPQN” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/510c4F92LqL.jpg” tag=”upbeat-jan-20″ width=”487″]

Drawbacks

Expensive

This is a big investment as it costs much more than regular stopwatches. This is a high-grade sports watch with many features. It isn’t for everyone, though there are certainly some people who could make good use of it. If the extra features sound like something you could do with, it might be worth the investment.

Basic Stopwatch

Keep in mind the stopwatch features themselves are very basic and it only really allows lap timers. Things like multiple splits, multi-row displays and advanced data tracking aren’t available on this watch. This makes the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link] best for people who will get actual use out of the swimming stopwatch itself and other features, and not so great for dedicated swim usage.

Amuz Sandhu — Sat, 15 Aug 2026 19:06:42 +0000

Triathlons are no ordinary sporting event. They challenge you mentally and physically across a trio of sports. For events of this level, you have to be serious about your training from the outset. It isn’t enough to just wing it, proper planning and monitoring can’t be overlooked. One of the areas you need to monitor is your heart rate, so it’s important to have a great, accurate heart rate monitor. Our overall pick for the best triathlon heart rate monitor would be the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link].

These trackers are ranked based on their abilities as heart rate monitors. Other features are considered a bonus though they don’t make up for a poor performance in the tracking area. If you’re looking for something ranked on its’ overall ability as a watch, check out our guide to the best triathlete fitness watches.

Best Triathlon Heart Rate Monitor

Best Triathlon Heart Rate Monitor – Garmin Forerunner 935

Garmin is a popular and trusted creator of fitness watches. They set a high benchmark, so it’s no surprise the top recommendation goes to their [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link]. It does a reliable job of heart monitoring via a wrist sensor and has plenty of other features too, including extremely accurate GPS location technology and data storage.

If you’re interested in Garmin watches and want to check out some alternatives, take a look at our guide to the best Garmin watches for triathletes!

Benefits

Compatible with Chest Strap

Most people would be surprised at a watch being the top pick purely because chest straps are considered more accurate. [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin 935[/easyazon_link] is compatible with certain chest straps though, so it gives the best of both worlds. Recommended are the [easyazon_link identifier=”B075RPZ3ZY” locale=”US” tag=”upbeat-jan-20″]HRM-Tri and HRM-Swim belts[/easyazon_link], giving waterproof ability alongside comfort and function.

Durable Battery Life

Battery life is massive on this watch, giving 2 weeks of performance in watch mode. The battery runs out quicker when in full-on tracking mode of course, though it’s still got more juice than many other watches and monitors.

Sturdy & Lightweight

Garmin is known for their smart and durable design across all ranges. This case is no exception, with reinforced polymers and chemically strengthened glass forming the body whilst a silicone strap gives extra reliability and a good amount of flex for comfort. It’s comfortable to wear and light enough to pretty much ignore.

Looks Fantastic

The [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] looks great when compared to alternatives. On looks alone, it would be tough to beat in either the heart monitor category, or the watch category. The rounded stylish face and the fact the digital display is high quality and customizable make it massively fashionable.

Accurate Monitoring

With the chest, strap monitoring becomes incredibly accurate. Even without it though the watch can hold its own, being unbeaten as a wrist-based heart rate monitor. The chest strap addition is also top quality and maintains this high standard.

Lots of Extras

There’s so much more to the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935[/easyazon_link] than heart rate monitoring. It’s capable of being a great all-around triathlon watch, able to give you all sorts of data on your training, including a lap counter for swimming pool work and a highly sophisticated and accurate location system. The system combines an advanced accelerometer and altimeter with accurate GPS to give precise information on distances and speeds.

Drawbacks

Expensive

The price is the main reason most people don’t go straight for this option. There are other popular options around at a lower price which do a good job too, though they also don’t feature the extra options of the [easyazon_link identifier=”B073WMPPQN” locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] and often can’t match it for heart rate tracking either. The difference in performance can be small though, so if limited on funds, there are other options.

Less Accurate Without Chest Straps

Neglecting the addition of a chest strap also affects the performance here. Chest straps perform more accurately than wrist monitors can and are therefore preferred by high-level athletes. This probably won’t be as big an issue if you’re a novice athlete, so take that into consideration as well. Those who want ultimate performance and tracking ability would do well to consider this feature-packed [easyazon_link identifier=”B0744PQMSZ” locale=”US” tag=”upbeat-jan-20″]Garmin 935 and chest strap combo[/easyazon_link].

[easyazon_image align=”none” height=”330″ identifier=”B0744PQMSZ” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/51DMqm4W6AL.jpg” tag=”upbeat-jan-20″ width=”500″]

Best Chest-Strap Only – Polar H7 Bluetooth Heart Rate Sensor & Fitness Tracker

This pick is perfect for anybody who doesn’t need the extras of something like the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link], or those who are interested in purely heart rate monitoring. The accuracy of a chest strap can’t be disputed and makes it the top pick in many ways. The [easyazon_link identifier=”B007S088F4″ locale=”US” tag=”upbeat-jan-20″]Polar H7 Bluetooth Heart Rate Sensor[/easyazon_link] is our top pick for this category and does an admirable job of tracking your stats.

Benefits

Compatible with Most Bluetooth Devices

The transmitter in this uses Bluetooth technology, so it can interact with most Bluetooth phones and watches. There is also an app available from Polar which is free on both iOS and Android systems, again compatible with the monitor and with some extra features too.

[easyazon_image align=”none” height=”500″ identifier=”B007S088F4″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31wIotFrb2L.jpg” tag=”upbeat-jan-20″ width=”500″]

Allows Extremely Accurate Readings

Wrist monitors usually use optical technology which is less accurate than ECG systems. ECG is the system preferred for medical uses because of its accuracy. It detects the actual electrical pulse triggered by your heart beating, making it unbeatable and spot-on at all times. This level of tracking gives you unbelievable control over your work-rate and development.

Comfortable & Stays in Place

The [easyazon_link identifier=”B007S088F4″ locale=”US” tag=”upbeat-jan-20″]Polar H7 Heart Monitor[/easyazon_link] is comfortable to wear, holding its’ position well. A regular complaint with chest straps is that they don’t stay in place once the exercise begins. In this case, you can move around as much as you like without dislodging the belt. It holds tight and does so without being uncomfortable to wear.

Waterproof

There’s a lot of chest strap options around for running though not so many for swimming. Triathletes need both. The [easyazon_link identifier=”B007S088F4″ locale=”US” tag=”upbeat-jan-20″]H7 chest strap[/easyazon_link] is capable of dealing with water just fine. Keep in mind that whatever you’re transmitting to also needs to be waterproof though, and most phones aren’t. This is one of the areas where the [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Forerunner 935[/easyazon_link] really pipped this out too, though you can also pick up a compatible [easyazon_link identifier=”B00TXHZIAI” locale=”US” tag=”upbeat-jan-20″]Polar watch[/easyazon_link] which does the tracking for you if needed.

Cheap

For a highly accurate heart monitor, this strap is available at a real bargain price. It’s much cheaper than even our mid-range watch and could probably even slip into the budget price range when on sale or with special offers.

[easyazon_image align=”center” height=”400″ identifier=”B0716L31YC” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/31B963DiTdL.jpg” tag=”upbeat-jan-20″ width=”400″]

Drawbacks

Some Athletes Dislike Chest Straps

As we said earlier, chest strap levels of accuracy are only really important to high-end athletes. For other users, chest straps can be unnecessary and even uncomfortable. The feeling of a chest strap bothers a lot of users and it can actually limit your bodies cooling mechanisms and cause extra sweating.

Usually Requires You to Carry Phone

Also because the [easyazon_link identifier=”B007S088F4″ locale=”US” tag=”upbeat-jan-20″]H7 strap[/easyazon_link] is a monitor and transmitter, there isn’t any way to view the data – so you need a receiver. The receiver would usually be a phone, though this means you also have to carry the phone whilst training, and most people can’t take their phones in the water either.

Best Mid-Range Watch – Fitbit Charge 2 Heart Rate

The Fitbit has been popular and successful from the launch of its original incarnation. Despite the [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Fitbit Charge 2[/easyazon_link]’s release date of September 2016, it remains a popular choice thanks to its functionality and is our top pick from the Fitbit range.

[easyazon_image align=”center” height=”500″ identifier=”B01K9S260E” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/41fEFbolIoL.jpg” tag=”upbeat-jan-20″ width=”387″]

Benefits

Good Accuracy

Of course any chest strap with ECG technology is going to be more accurate than the [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Fitbit Charge 2[/easyazon_link]. Do you really need that level of accuracy though? If not, this watch offers a high level of accuracy compared to other optical devices, with the convenience and comfort of a wristwatch monitor.

Light & Comfortable

A sleek design and lightweight materials combine to give you a comfortable heart tracker. It doesn’t get in the way or feel bulky. Most users forget they’re even wearing it after a while.

Large Display & Easy to Use

Fitbit market their products as being accessible and easy to use. The large display adds to this because its easily viewable and gives a larger touchscreen area. The range of information is limited though there’s still more than just basic heart rate. Monitoring of sleep habits, steps, and calories burned are just some of the extras on offer. The way this watch is designed makes it simple to use from the first try as well.

[easyazon_image align=”center” height=”500″ identifier=”B01K9S260E” locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/3173XFlQpjL.jpg” tag=”upbeat-jan-20″ width=”500″]

Looks Great

The sleek design isn’t just lightweight either, it gives the [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Charge 2[/easyazon_link] a great minimalist appearance. Having interchangeable straps helps here too because you can pick different colors or even options like leather straps, making it totally customizable.

Drawbacks

Not Waterproof

While being water-resistant, the [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Charge 2[/easyazon_link] isn’t waterproof. It can be used for running though for swim training you’re going to need an alternative or leave the monitoring altogether. This is a big sticking point for some triathletes who really want to monitor swim performance separately.

Best Budget – Letsfit Fitness Tracker with Heart Rate Monitor

As our budget pick, I’ve selected the [easyazon_link identifier=”B07B3S3HB6″ locale=”US” tag=”upbeat-jan-20″]Letsfit Fitness Tracker[/easyazon_link]. It looks similar to the Fitbit and has many of the same features, though does have a couple of drawbacks in comparison to our other choices, as you would expect from a budget item.

[easyazon_image align=”center” height=”500″ identifier=”B07B3S3HB6″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/51pAWYXFZWL.jpg” tag=”upbeat-jan-20″ width=”500″]

Benefits

Cheap

The biggest reason why this is popular is the low price. It’s cheap enough that even if it does break or get lost after a while, that won’t really be a huge issue. You could by a few of these for the price of a good [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Fitbit[/easyazon_link], and way more for the price of a [easyazon_link identifier=”B06XGD6CS4″ locale=”US” tag=”upbeat-jan-20″]Garmin[/easyazon_link].

Comes with Extra Features & Good Tracking

Despite the cheap cost the [easyazon_link identifier=”B07B3S3HB6″ locale=”US” tag=”upbeat-jan-20″]Letsfit Fitness Tracker[/easyazon_link] does a respectable job of heart monitoring, giving plenty of bang for your buck. On top of that it has extra features like a calorie counter, sleep monitoring, and even limited phone connectivity.

Drawbacks

Less Reliable Than Alternatives

Lower price means lower quality materials and a lower level of build quality. The straps on these can start to wear down after a few months of heavy use and sometimes break. Replacements are available through and the entire watch can be replaced at a low cost if needed.

[easyazon_image align=”center” height=”500″ identifier=”B07B3S3HB6″ locale=”US” src=”https://images-na.ssl-images-amazon.com/images/I/51eARIFSV6L.jpg” tag=”upbeat-jan-20″ width=”500″]

Not Waterproof

The [easyazon_link identifier=”B07B3S3HB6″ locale=”US” tag=”upbeat-jan-20″]Letsfit Fitness Tracker[/easyazon_link] isn’t waterproof either, so it’s only usable for running and cycling, not swimming. It’s difficult to find a budget option that offers waterproof tracking so this consideration isn’t such a big deal for the budget selection.

Bottom Line – Best Triathlon Heart Rate Monitor

Overall it’s important to know what you need upfront. Are you in need of highly accurate ECG monitoring? Or is optical enough for your needs? Comfort and convenience also play some role in the chest strap vs wrist monitor debate, with the price being the final decider.

For newcomers a [easyazon_link identifier=”B07B3S3HB6″ locale=”US” tag=”upbeat-jan-20″]LetsFit Fitness Tracker[/easyazon_link] will do fine, and the price difference makes this my preference over even the [easyazon_link identifier=”B01K9S260E” locale=”US” tag=”upbeat-jan-20″]Fitbit Charge 2[/easyazon_link]. If you do need the chest strap accuracy I’d go for the [easyazon_link identifier=”B06XFZQZ3Q” locale=”US” tag=”upbeat-jan-20″]Garmin Forerunner 935 Tri-Bundle[/easyazon_link] so you get the best of all categories. The level of athlete who needs ECG accuracy will also need the other features available on this watch, like GPS. The [easyazon_link identifier=”B0716L31YC” locale=”US” tag=”upbeat-jan-20″]Polar H7[/easyazon_link] gives a much cheaper alternative, although you’d need to carry a phone (or alternative receiver) with you as well, and there aren’t any extra features like GPS.
