Train more effectively with our premium heart rate monitor. When worn around your chest during an activity, it wirelessly transmits your heart rate to your compatible device for instant feedback on how hard you’re working.

The strap is made of a comfortable soft fabric. Adjust the size to your body for secure fit during your activities.

Pair it with your compatible device just once, and it will automatically recognize it each time. Optimized for use in crowded areas like the gym and road races, it won’t pick up any signals but your own.

Taking care of it is a snap. The plastic heart-rate module is removable from the strap so you can wash the strap as often as needed.

Enhance your triathlon training and experience with the HRM-Tri Heart Rate Monitor from Garmin. This triathlete-specific device records and stores your heart rate data on land and in the water, giving you a more complete picture of your heart rate performance during your triathlon or triathlon training. It stores up to 20 hours of activity data and automatically sends it to your separately available Garmin device—for example, the Forerunner 920XT. If you're recording heart rate data while you're in water, the HRM-Tri will send that data once you've exited the water to your compatible device.

In addition to recording heart rate data, the HRM-Tri also houses an accelerometer that enables it to track three running dynamics: your cadence, vertical oscillation, and ground contact time. Tracking and understanding these metrics can help you become a more efficient runner and triathlete, as they provide real-time feedback about your running form.

HRM-Run provides 6 running dynamics metrics:

  • Cadence — number of steps per minute
  • Vertical oscillation — degree of ‘bounce’ in your running motion; displays the vertical motion of your torso, measured in centimeters for each step
  • Ground contact time — amount of time in each step that you spend on the ground while running; measured in milliseconds
  • Ground contact time balance — displays the left/right balance of your ground contact time while running (displays a percentage); for example, 53.2 with an arrow pointing left or right
  • Stride length — length of your stride from 1 footfall to the next; measured in meters
  • Vertical ratio — ratio of vertical oscillation to stride length (displays a percentage); a lower number typically indicates better running form
