Important Considerations When Choosing a Triathlon Watch

Battery Life

Battery life is one of the most important considerations when choosing a triathlon watch. Depending on the length of our race, you’ll want a watch that can last for the whole race. There’s nothing worse than having your watch die halfway through your run.

There are multiple factors that go in to a triathlon watches battery life. The size and composition of the battery itself is the most important. You can check the expected battery life in the product details. Another to consider is the use of GPS. GPS drains batteries substantially and considering you are likely using GPS for your training and races, this is one of the most important numbers to consider.

Everyday Usage

It’s also important to consider how you’re going to use the watch on a daily basis. Are you going to wear the watch all day or just during your trainings? Some triathlon watches are more suitable for everyday usage and include features such as music, payment, and resting heart rate, while other watches are more utilitarian without the features you may use everyday.

Types of Activities

Every watch on this list tracks runs and cycling via GPS, but only a few track open water swimming via GPS. If that’s important then you’ll want to make sure that box is checked when you’re buying a new triathlon watch. Outside of the basic swim, cycle, run, some watches track other activities such as weight lifting and even snowboarding. Our reviews contain listings of all activities tracked by the watch, so it’s important to know which activities you plan to do and make sure your watch can support it.

Budget and Cost

Triathlon watches are a big investment. Outside of the bike, the watch is one of the most expensive pieces of equipment a triathlete owns. Keep in mind that a solid triathlon watch will last you years, and thousands of miles on the pavement and in the water. It’s not the place to go cheap, so if you can afford to spend a little extra for a watch with all the features you need it will be well worth the additional investment. Your budget will likely dictate what kind of watch you can buy, as costs range from around $100 to well over $600. Figuring out how much you can afford is the first starting point when choosing a new watch.

Apps and Metrics

Different watch brands have different apps and metrics. Garmin is one of the most popular watch brands and has a solid app that all of its watches use. The Garmin Connect app is one of the best activity tracking apps on the market so that automatically gives Garmin watches the edge. Other software apps, such as the Fitbit Connect, are also serviceable services for tracking your training.

Another important consideration is metrics. Understanding which metrics are available in each app, such as VO2 Max for Garmin Devices, will help differentiate watches and help you understand what you need.

Top Triathlon Watches for 2021

1. Garmin Forerunner 935 ($269.99) – Best Overall Triathlon Watch

This is the watch that I personally use and is the best triathlon watch on the market. It can easily track most sports, including the most important running, cycling, and open water swimming. One of the biggest pros to this watch is it’s battery life which should last for any Ironman race. This watch does not only delivery during races, but is great for ongoing training and tracking. The Connect IQ app for iPhone and Android easily tracks workouts, heart rate, VO2, and many other metrics. In addition to training, the watch tracks everyday metrics such as resting heart rate and sleep. That makes the Garmin Forerunner 935 the best all around triathlon watch.

Cool Garmin 935 Features – Garmin’s Training Status

A few of the best features that I use often with this watch is the ‘Training Status’ and VO2 Max. Training status measures your current training load and overall fitness (things like heart rate and performance) during your workouts to determine what your training status is.

The different statuses are peaking, productive, maintaining, recovery, unproductive, detraining, and overreaching. You can read more about those on Garmin’s website but in general these are pretty good indicators of how you’re progressing.

I have found one problem with the training status – when doing brick workouts it does not take into consideration you did two workouts back to back, so your run (for example) after your bike could classify you are unproductive since your heart rate and performance is likely less than typical.

Cool Garmin 935 Features – VO2 Max Calculation

VO2 Max is a calculation of how efficiently your body is using oxygen during your workouts. Higher VO2 Max numbers have been tied to better fitness, performance, and overall health. The Garmin 935 does a good job tracking your ongoing VO2 Max and you can track your progress over the course of weeks or months as you build your fitness.

This is a great overall feature and is generally considered relatively accurate, plus it beats the tubs and lab testing that athletes normally have to go through. Lastly, you can compare your VO2 Max to others in your age group and the watch will give you an Top % and your fitness age, pretty cool!

Garmin Connect Software and App

One of the places where Garmin watches really shine is their software and app. When you complete a workout it’s automatically uploaded to the Garmin Connect app on your phone or on the web. From here you can track your training and workouts. The app contains a ton of useful information like stress level, heart rate, intensity minutes, and some other unique metrics such a VO2 Max and Training Load.

VO2 Max and Training Load Explained

One of my favorite features of the Garmin watch is the ability to track VO2 Max and training load. VO2 Max is a measurement of the maximum amount of oxygen an athlete can use during exercise. It’s a great measurement both of heart health and of athletic endurance. You can track this via the app and see the improvement.

The next metric is training load. Training load measures the amount of training and level of exertion during a rolling 7 day average. It will tell you if your in recovery, maintaining, productive, peaking, or overreaching in your training and also give you optimal recovery time after each exercise.

2. Garmin Forerunner 945 ($589.99) – Most Advanced Triathlon Watch

The Garmin 945 is by far the most advanced triathlon watch, containing many features of the 935 with the addition of more everyday applications for music, maps, and payment.

Difference Between the Garmin 935 and Garmin 945

In general the two watches have the same features for triathletes, but the Garmin 945 is more of a lifestyle watch plus triathlon watch. The main difference is the 945 contains music, maps, and payment abilities in addition to the normal activity features of the 935. Another difference most people notice is the price difference between the two – on Amazon the Garmin 935 is $269.99 while the Garmin 945 is $589.99.

3. Fitbit Versa 2 (Price not available) – Best Smartwatch and Triathlon Watch

The Fitbit Versa 2 is a watch that I have owned for many years and is one of the best smartwatch and triathlon watch. The easy to use interface is perfect for the beginner triathlete or Sprint/Olympic triathletes. This is the perfect watch if you want a mix of easy to use smartwatch and solid activity tracker for swimming, cycling, and running. One of the weaknesses of this watch is the battery life with GPS, which potentially could go out during a longer Ironman. Another weakness is the inability to track open water swimming. The watch does a great job of tracking laps in a pool, but is unable to use GPS to track swimming in open water.

Lens Material – Corning® Gorilla® Glass 3
Strap – Woven band made from polyester
Size – 1.56 x 1.59 x 0.47 inches
Display Size – 1.57 inches in diameter

Fitbit Connect Software and App

The Fitbit Connect app and website is an easy to use activity tracker where you can check on things like heart rate, steps, and activities. Although the tracking is accurate and easy to use, it is a very basic platform and only has very specific information.

The interface is easy to use and tracks everything you need from steps to ongoing resting heart rate. Additionally the app will tell other lifestyle activities such as you how well you slept and how many calories you burned during the day (through normal activities + active workouts).

4. Garmin Fenix 6X Pro ($632.51) – Best Watch for Extreme Triathlons

If you’re planning on using your watch for some extreme hiking, mountain climbing, or skiiing, then this watch is the one for you. That is why we are ranking the Garmin Fenix 6X Pro the best watch for activites beyond triathlons. It contains all of the features of the 935 above, but is a bit larger, made with more durable material, and lasts longer due to solar charging. You hear that right, the watch has an option for solar charging in case you’re on a long hike. This extends the battery life substantially in regular mode, but only for an hour in GPS mode.

Another big differentiation is the ability to load maps (trail maps, climbing routes, and ski maps) on to the watch. This can be useful when training for extreme triathlons in mountains or remote trails.

Lens Material – Corning® Gorilla® Glass DX or Sapphire Crystal

5. Polar Ignite ($199.90) – Best Budget Triathlon Watch

The Polar Ignite is an intuitive feature filled triathlon watch that features a slimmer and lighter design than other watches on this list. This watch is a great starter triathlon watch in the $200 range and has all the features needed, including running, cycling, swimming, and a ton of other activities (see specs).

Polar Ignite vs Polar Vantage

The Polar Vantage is also a great multisport watch that is a bit of a higher price but arguably better for triathlon events. The battery life is higher (30 hours vs 17 hours with Ignite) and there are some addition metrics around things like cadence and stride. But overall we don’t feel the increase in price is worth the extra money for the Vantage over the Ignite.

Triathlon Watch FAQs

Can you use the new Apple Watch as a triathlon watch?

Technically yes – the Apple Watch contains all of the features needed for triathlon activities, including open water swimming, cycling GPS, and running GPS. The main problem is battery life, which would barely last you through an Olympic Triathlon. So in general the watch could be an option for training and shorter triathlons, but not a good option for any serious triathlons.

Do I need a triathlon watch?

If you’re just getting started and training for a Sprint or Olympic distance then you probably could go without a watch. The amount of time training and racing don’t really warrant the additional features that many nice triathlon watches have. Anything over a Half Ironman, a triathlon watch is probably a top priority. You’ll want to track your runs, bikes, and swims and also have a watch that helps you pace during the race. Triathlon watches are meant for heavy duty training that comes with training
