GARMIN HRM-TRI heart rate belt, specific for triathlon, works in the water during the swim fraction
Compatible with 920XT, EPIX, FENIX3 models
  • Specifically made for triathletes
  • Our smallest and lightest heart rate monitoring system (HRM)
  • Comfortable band, easily adjustable and very compact under the wetsuit
  • Stores and sends heart rate data from your swim training to your Forerunner® 920XT or ALTRA compatible device
The HRM-Tri stores heart rate data as you swim and sends it to your device when you get out of the water. Our extremely small and lightweight module adapts to chest width and is perfect to use even under the wetsuit for minimum bulk. Its rounded and soft edges, with covered seams, make the band very comfortable even out of the water for pedaling and running.

Running dynamics

HRM-Tri also has an accelerometer in the module just like the HRM-Run belt, which measures the movement of the torso in order to calculate the three fundamental running dynamics 2 :

  1. Step cadence: The number of steps taken per minute while running. Displays the total steps (left and right combined).
  2. Vertical Swing: Displays vertical movement of the torso (measured in centimeters) while running. HRM-Tri is compatible with many ALTRA fitness products but displays heart rate only when paired with them.
  3. Ground Contact Time: The contact time of each step with the ground while running (measured in milliseconds).
