Things To Consider Before Buying The Best Garmin Watch For Triathlon

A good triathlon smartwatch has many additional features over and above the ones a regular running smartwatch has. First, a triathlon vest must be waterproof. Without one, it would be pretty tricky to wear the whole time.

To get the perfect triathlon Garmin watch, you should consider the following things:

Fitness Levels

Garmin adapts its timepieces for beginners, intermediate level, and advanced levels of multisport activities. For example, if you start a daily running session for just one training, you will not need a triathlete watch. 

Make sure to check to what fitness level the watch is designed. It is not necessary to pay for features you will not need for a specific time.

Fit And Comfort

Make sure that the watch you will buy is comfortable because the races will last for a longer time. To ensure that the watch must not be uncomfortable.

To obtain a comfortable fit, you will need a flexible silicone strap and smooth housing material.


Nearly any Garmin indeed watch you will have a base level of performance and GPS tracking features. 

GPS protocols like GLONASS and Galileo can be beneficial for outdoor triathlons, especially in nature. 

Heart rate monitors are industry standards for fitness-oriented smartwatches. Make sure you check the specifications for each look to make sure it’s got what you want.

Check For Triathlon Settings

This guide may help you obtain the best Garmin watch for triathletes. But just to be sure, always make sure that it has a triathlon frame in the activity profiles before buying. 

This adjustment is not mandatory, but it will make the triathlon experience much more practical.

High Quality

If you do not need your new tri watch to interrupt after, by chance falling off, you should go with the high quality and rugged material watch.

Also, make sure that this watch must contain Sapphire crystal lenses and a sturdy casing or Gorilla Glass.

Battery Life

Triathlon races can last anywhere from a few hours to a few days. So make sure that your watch’s battery can last up to the end of the race.

The good Triathlon watch should be able to last at least 6-8 hours in GPS mode, so it doesn’t die on the wrist shortly before the end of the race.


Which Garmin watch is more accurate?

The accuracy of the Forerunner series of Garmin is more accurate. Among this series, Garmin Forerunner 945 is the most accurate Garmin watch for Triathlon.

How does Triathlon mode work on Garmin?

With Triathlon mode on one watch, you can track your swimming, cycling, and running in one activity. You can focus on your running, and you don’t have to worry about starting and saving each activity separately. Unfortunately, not all sports watches have this feature.

Can you answer calls on Garmin watches?

Yes, you can quickly receive calls from your Garmin Vivoactive 4. The watch has a built-in speaker and microphone that allow you to take calls and speak clearly.


From the above reviews, guide, and research, we concluded that the Garmin Forerunner 945 is the winner and works perfectly in your triathlon race.

Although, other Garmin watches that we reviewed are also best for triathlons. You can buy based on which features you need.

Also, to get the perfect Garmin watch, make sure you consider buying as mentioned earlier guide.
