Best GPS Watches for Triathletes – Buyer’s Guide

The watches for the triathletes are able to track running, cycling, swimming, and many more activities. And they are totally different from other running and swimming watches.

Basically, you don’t need every single feature on your triathlon watch. But if you have more features then these allow you to act freely and focusing your training/racing, instead of sticking in your watch.

So, what should you consider before purchasing the best GPS watches for triathletes ?

This is obviously the most important factors for the triathlon watches because triathletes need to switch between the multiple modes.

A watch which is having this feature allows you to switch quickly with the help of a single button. You can change mode according to your activities: running, cycling or swimming. Moreover, when you change the mode, the display also changes accordingly, for example: if you change the mode to swimming, then the display will show you data related to swimming like lap count, timing etc.

Other watches don’t have this feature and they have the manual stopping of the activity, you have to configure the setting for particular activity every time. Apart from that, you will also unable to review the workout as a single activity post-race.

The best GPS watches for triathletes should be compatible with common cycling accessories like – power meter and cadence trackers. These features allow you to track more data while riding.

First of all, for swimming the triathlon watch should be waterproof, that’s obvious. But what are the benefits of that watches which can track distance, stroke and some other swimming related metrics?

These watches can track stroke count, laps. And some watches even allows you to track, that which types of stroke you are using. And this data can be gathered while you wear these watches on your wrist.

But, those GPS watches that don’t have swim features, how can you track swim with them?

These GPS watches can lose signal when they dipped in water more than an inch. So, for tracking the swim properly you have to put them under your bathing cap, and this will keep them above to maintain the GPS signal.

Basically, the quick-release system allows triathletes to easily move the watch from wrist to the handlebar mount. If you typically ride with aerobars then this feature is very crucial for you.

However, if you are comfortable with watches on your wrist while riding then this feature isn’t too important. Additionally, there is also another option for this, you can buy them seperately from Amazon around 10$, and mount them manually, but it is more time consuming than the quick-release kit.

This is also one of the most important features of the triathlon watch. If you are planning to compete in longer races like Ironman triathlon, which is one of the most difficult one-day sporting events. Most Ironman events have a limited time of 17 hours to complete the race, so these GPS watches might not last the entire race.

Even, better GPS watches like Garmin Forerunner 735XT and Polar V800 have maximum battery life up to 10-14-hour range.

Finally, the triathlon watches should also thin in size, this is not the major requirement but it is also important. The thin watches for athletes allow them to easily get the wetsuit off.


I hope you have gotten your best watch for the triathlon successfully.

Along with features, the comfort level is also the most important factor for triathlon watches, so make sure that watch you choose should fit with your wearing style. You can also check out quick-release supported watches that are convenient when cycling.

Best of luck, for your triathlon contest!
