Black and copper smartwatch

Suunto 7 | $400

Rating: ★ ★ ★
Weight: 68g

Basics

This watch has a blend of full lifestyle functionality and medium-level single-sport training capabilities on a beefy touchscreen smartwatch.

  • Fantastic GPS navigation display, offline maps, and popularity routing
  • Good compatibility with Android via WearOS (works with Apple iOS as well)

Dark green and rose gold smartwatch

Apple Watch Series 6 | $400 (40mm) | $430 (44mm)

Rating: ★ ★ ★
Weight: 47.1g

Basics

A lifestyle watch with an impressive level of bells and whistles standard in the Apple suite. New ECG and heart-rate features, along with Apple Fitness+, make it appealing for general fitness, but without the tri-specific functionality of a more sport-focused watch.

Pros

  • Connection to a phone number enables some truly mind-blowing lifestyle features
  • New ability to track ECG and heart-rate variability are nearly medical-grade
  • Well-designed and pretty
  • Comes in 40mm and 44mm sizes, with a variety of higher-end bands options

Cons

  • Surprisingly poor battery life
  • Workout modes are lacking in the features triathletes would expect
  • Requires an iPhone
