Best wearables for endurance athletes: tested recommendations

A GPS watch is not always the right tool. Chest strap heart rate monitors outperform optical wrist sensors in almost every sport at high intensity. Recovery trackers provide strain and readiness data that a training watch cannot replicate without constant wear. Running power meters add a dimension of effort measurement that pace and heart rate alone cannot supply. This section covers the wearable devices that sit alongside or replace a sports watch in a serious training setup.

The recommendations here come from the same testing framework applied to sports watches on this site: extended use in real training conditions, multi-device comparisons against reference sensors, and assessment of platform software as well as hardware. A device with accurate sensors and poor software is not recommended without that caveat being clearly stated.

Recommendations by category

  • Best wearables for female endurance athletes: devices and platforms that account for the female athlete’s physiological profile, menstrual cycle tracking, and RED-S risk monitoring.
  • Best recovery tracker: WHOOP, Oura, Garmin Body Battery, and competing platforms compared on readiness accuracy, sleep staging, and training guidance.
  • Best heart rate monitor: chest straps, optical arm bands, and pod-based sensors ranked by accuracy, connectivity, and compatibility with Garmin, Wahoo, and third-party platforms.
  • Best running power meter: Stryd versus Garmin Running Power versus competing footpod and wrist-based solutions, with accuracy data from controlled testing.

Female athlete technology

The physiological differences between male and female endurance athletes are material and are increasingly reflected in wearable platform design. Cycle tracking, RED-S risk indicators, and female-specific training load adjustments are now available across Garmin, Polar, and Whoop. The dedicated guide covers which platforms implement these features meaningfully and which treat them as a checkbox. For broader coverage of technology relevant to female endurance athletes, see the female athlete tech hub.
