Garmin Forerunner 935

Best Triathlon Running Watch

Why people love it
  • The watch built for running, cycling, and swimming
  • Sleek and lightweight, yet packed with features
  • One of the most versatile non-smartwatches ANYWHERE

Comes with all the features you need for your triathlon, compatible with heart rate straps, displays a full range of performance and fitness metrics, one of the most versatile running watches on our list, sleek design, and good battery life.

The wrist heart rate monitor design is flawed, and the watch is pretty pricey.


Performance: If you want performance, this is the watch for you! It's sleek, slim, and loaded with features to help you measure and analyze every aspect of your performance. From heart rate monitor to VO2 sensors to training programs to notifications from your smartphone, this little watch is as high-tech as it gets without being a proper smartwatch.

The battery life is surprisingly long—up to 24 hours in GPS mode—so you'll never have to worry about running out of power mid-triathlon. It's water-resistant up to 100 feet and built with a solid band that will stay firmly in place no matter how fast you swim.

Features: While the wrist heart rate monitor isn't the most accurate, it's easily paired with a Garmin chest strap and other accessories to make tracking your performance a breeze. The algorithms of the watch will actually learn your fitness levels and performance, helping to push you to your limits without causing strain. It will literally tell you if you're working too hard or not hard enough.

The watch interface is designed for convenience, and you can see all the important metrics at a glance. Better still, you can customize the interface with the widgets and data you want displayed. The numbers and words are easily legible and very sharp, and you'll find the interface is very user-friendly.

Price: At close to $480, this isn't a watch for casual runners. However, for serious triathletes who need a multi-sport watch capable of keeping up with their hardcore training and racing, this is worth every penny!
