Product Description

Enhance your triathlon experience by pairing HRM-Tri with your Forerunner® * specific models only. The HRM-Tri stores heart rate data when underwater, then forwards the information to your device once your finished. Our smallest and lightest module fits within the width of the strap. Its soft, rounded edges and covered seams make the strap super-comfortable out of the water, too.

Also features:

Running Dynamics

HRM-Tri also has an accelerator in the module that measures torso movement to calculate 3 running metrics:2

  1. Cadence — the number of steps per minute. It displays the total steps (right and left combined).
  2. Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters). HRM-Tri is compatible with several other fitness products but will only display heart rate when paired.
  3. Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
