Best Triathlon Watch

A watch is considered to be the best tool to keep track of time. Nowadays, watches have many functions that many athletes consider to be very useful when it comes to keeping track of their exercise routines. Since there are 3 events to a triathlon, we decided to focus on watches that come with tracking features for all 3 events: swimming, running, and cycling. When you are planning to be participating in a triathlon and want to buy a smart watch to keep track of your progress, then you must look for the watch that has the ability to measure the 3 major activities combined like the open swim mode, running, and cycling lap timer.

Our #1 Triathlon Watch Choice!

Garmin Forerunner 910XT GPS-Enabled Sport Watch

Why we love it:

  1. GPS-enabled for multisport athletes
  2. Utilized for swimming, running & cycling – water-resist up to 50m
  3. 20 hrs battery life max

Here are some features you need to know when shopping for a triathlon watch. Most smart watches that measure running will also have a cycling mode. Additionally, cadence can also be used to measure rotations per minute. Watches also have an internal accelerometer that will do a fairly decent job of tracking your fitness levels. But if you choose to pair your device with a separate heart rate sensor, you will increase your accuracy by a great margin.

Swimming is also included when engaged in a triathlon and another thing to look for in a watch is the waterproofing, otherwise known as ATM. Having a watch with an ATM of 5 or more is considered suitable for swimming. Swimming efficiency or SWOLF is a tracking metric that measures swim efficiency and this can be a useful metric for tracking and improving your swim speed.

For the running metric, there is a feature known as GCT that is a metric that tracks the total time your foot takes to hit the ground and lift off, and vertical oscillation is the amount of time you bounce up and down with each step. Now, to help you decide which triathlon watch to buy, here are some of the best you can get today.
