Best Triathlon Watches

Selecting the best triathlon watch is like when you’re buying a smartphone, as you want it to have the best features for your triathlon performances. It’s a bit tricky and you don’t want to get distracted by its functions either.

What’s to say about triathlon watches briefly?

As there are three events during a triathlon, you want a watch that includes tracking functions for all the three main activities: swimming, running, and cycling. Finding a watch that manages to offer excellent performance for all three events isn’t easy, for sure.

There are many watches out there that come with all sorts of functions that you may use for impressive workouts, cycling, or running. You don’t need the sophisticated features; sometimes it’s ok to have just the basic ones.

How to select your triathlon watch?

Several functions are fundamental when selecting a triathlon watch, and you should scroll down for the details. The more you know about what you need in a triathlon watch, the easier the selection process is going to be.

  • Swimming functions

With swimming as one of the triathlon activities, it makes sense that the watch should provide effective monitoring of your swimming activity.

  • Swimming efficiency- Also known as SWOLF, the functions measures swim efficiency. It adds the number of strokes per pool length, split to the entire time per length. It’s an excellent metric to use for tracking and increasing your swim speed. It’s not enough, though, when you’re competing in the triathlon.
  • Swimming metrics- You need to check the ATM and the waterproofing altogether. An ATM of 5 and higher than 5 is suitable for swimming.
  • Open water swim mode- Not all watches come with open water swim mode, even if many of them are waterproof. With the majority of triathlon competitions taking place in open water and not in swimming pools, the lack of function can pose some problems. If you want precise triathlon tracking, look for a watch with this function.
  • Running metrics

Most fitness trackers and smartwatches come with run tracking function, but only some of them include advanced tracking functions that you need in triathlon. Here are some of the features to look for in a triathlon watch:

  • Cadence, ground contact time&vertical oscillation- Cadence is about the steps per minute, and it depends on your weight, height, and stride length. GCT (Ground contact time) tracks the time your foot needs to hit the ground and lift off. The vertical oscillation is the time you need for bouncing up and down your steps.
  • Cycling functions

It’s pretty standard for smartwatches that track running to include cycling mode as well. Cadence may also work for measuring rotations per minute. With the majority of smartwatches including GPS functions, it makes sense that you may measure both distance and speed.

You should also consider a watch that comes with Power Meter as it’s going to increase the precision of your cycling tracking. Keep in mind that this type of watches isn’t cheap.

  • Heart rate function

Many watches have an internal accelerometer that tracks the fitness functions. If you’re determined to obtain better accuracy for your activity, you should get a device with a separate heart rate sensor.

Back in the days, heart rate monitors weren’t standard. The situation has changed, and most watches today can work together with a heart rate sensor. You need this sensor for getting better information on your fitness activity.

Is the design or the build outstanding on a triathlon watch?

But it’s not only the specific functions that you need to consider when selecting your triathlon watch. Apart from good build and durability, here are a couple of things to pay attention to:

  • The strap

When you’re cycling, you want to have a watch that you may easily attach to the bike’s handlebars. It’s going to be a lot easier to see it in the aero position if so. You can use foam blocks for strapping your watch to the bike, the same way you’d put it around your wrist.

You may find models that come with a quick-release kit, which lets you remove the watch from the wrist strap nice and smooth, only to attach to the handlebars later on.

  • Thin design

As you’re going to swim, you need to wear a wetsuit and remove it, at some point. A dependable triathlon watch is really thin so that you remove the wetsuit easy. Even if a thick watch may look more rugged and robust, it’s going to make the pulling of the wetsuit sleeve a lot more complicated.

One last piece of advice before you go shopping

Many things matter when you’re selecting a triathlon watch. Apart from the functions for swimming, running, and cycling, you also need it to be able to count calories, pace, elevation gain, and so on. Also, you should take a look at the overall build and battery life. The last thing you want is to have a great watch only to realize in the middle of your cycling that the battery is gone.
