Best Triathlon Watches

There was a time when the sports watches could only offer time and heart rate and offered little additional value.  But with the proliferation of GPS-enabled devices, modern best triathlon watches are quite advanced in their offering and can help any athlete train with more precision. The watchmakers have turned the simple watches into complex fitness tracking tools. If you are running a triathlon and looking for a smartwatch, you need to look for all these modes. Through comparing different watches available in the market, we have finally selected the top four gears you should get your hands on if competing for a triathlon.

Garmin Forerunner 920 

Let’s cut to the chase: The Garmin 920 is our favorite triathlon watch.  It is the time that we realize that the idea of knowing our fitness abilities is old and outdated. The world is progressing rapidly regarding technology, the reason technology exists it because it can reshape our spirits and rebuild us in a new way possible. One might argue that coping with technology is costly and all of the people cannot afford it. We agree. The power and features of this watch are far more superior to the plethora of watches that are present in the market, so the price doesn’t hurt.


Many people complain that the sports watches available in the market are not comfortable to wear because of the larger size. Garmin Forerunner 920 is no different regarding size, but the larger size has an advantage as the buttons on the front and side are easy to locate.


One of the most promising features of Garmin Forerunner is its ability to track your runs accurately. It can monitor your average speed, heart rate, and regular alerts to keep your speed up. It is also an excellent step tracker and is smart enough to tell you how much fitter you are getting with time. On the other hand, it is a reliable partner in swimming with a very delicate GPS tracker, SWOLF tracker, and a length tracker. The length tracker helps you to calculate the number of times you have come up and gone inside the water. The SWOLF tracker helps to calculate the strokes each length is taking. One of our favorite features, though, is a calculator on how much rest time you should have based on your most recent workout — and if we have learned one thing, it is that most triathletes underestimate the importance of rest.

Tom Tom Multisport

The greatest feature of TomTom Multisport is its innovative design and one-button usability. It can track all three modes in a triathlon. As compared to the other sports watches, TomTom Multisport is quite cheaper but lacks the accuracy in swimming mode.


The watch is designed to ensure comfort and performance at the same time. It has a large LCD with a single-button menu system. It comes in a gray and dark pink color.


With the one-button control system, it becomes relatively easier to operate the watch as you don’t need to remember what button does what. The button acts as a D-pad, and you can operate the watch by simply scrolling within the menu. This watch is aimed at tracking your abilities during swimming, cycling, and running. It can work as a pedometer, calorie tracker, distance calculator, GPS-system, and stroke detection. The swimming mode is useful for lap pool swims, but not ideal if your main swimming is done in open water.

Polar M400 GPS Watch

The M400 is a new class of fitness wearables combined with simplicity and high performance of expensive watches in a single device. It is surprisingly functional and a great option for the fitness enthusiast buying their first proper running watch. The professional triathlon runners can use it well, but it lacks underwater heart rate monitoring and route navigation.


Unlike the bulky triathlon watches, M400 is incredibly slim and light. Being less obtrusive than the other GPS-tracking watches, it looks perfect even on the skinnier wrists. The five buttons are smartly placed so that you can operate the watch without any stress.


The M400 is a perfect workout companion that functions as an activity tracker and fitness band. The watch has different modes depending on the activity you are performing. You can choose from “Aquafitness” to “Yoga” and even “Classic Roller skiing.” It is waterproof, but the company suggests that you do not push buttons underwater and it is not meant to go far below the water surface.  One feature we like is the option of free training plans to be download to the watch, making it a true workout buddy.

Fitbit Flex 2

Despite having no display and heart tracking, Fitbit Flex 2 is completely worth the compromise. Thanks to its arm-band like design and effectiveness even in the water, it is proving to be one of the trusted triathlon watches. It has a long battery life and sleeker design with the ability to track all the activities and sleep. It is connected to your phone and shows all the activities through an application.

With the strong brand of Fitbit and the likelihood of the Fitbit lineup growing in the future, it is intriguing for triathletes to think about building their training database on the Fitbit platform.

A very important distinction, though, is that the Flex 2 is not meant to be used to glance at your speeds and mileage within a workout — and that is exactly what many triathletes need.  Instead, it is a great tool for looking back at your workouts over time and understanding how your training has been trending.

Non-Swim Options

The devices listed above are all listed because of their ability to handle all three swims in a triathlon – the swim, the bike, and of course the run.  If you are willing to not wear a watch in the swim and only track your cycling and running performance, your options open up considerably.  If you are not taking them in water, you can consider several more Garmin and Fitbit models, including the Fitbit Blaze workout watch.

Final Thoughts!

The choice of a triathlon watch depends on your usage. If you are a professional competitor, you should go with Forerunner 920. It has all the necessary features to help you during your training. For all the fitness enthusiasts, not willing to spend much, the rest three products are perfect and can track your activities accurately.
