Product Description

Enhance your triathlon experience by pairing Garmin HRM-Tri Heart Rate Strap with your Forerunner® 920XT1. The HRM-Tri stores heart rate data when underwater, then forwards it to the 920XT.

Top Features of the Garmin HRM-Tri Heart Rate Strap

Specifically designed for triathletes

Our smallest and lightest heart rate monitor (HRM)

Comfortable, easily adjustable strap

Stores and forwards heart rate data to Forerunner® 920XT

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.

Running Dynamics

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

Cadence — the number of steps per minute. It displays the total steps (right and left combined).

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.

Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
