Enhance your triathlon experience by pairing HRM-Tri with Forerunner 920XT. Stores heart rate data when underwater, then forwards it to the 920XT. Garmin's smallest and lightest module fits within the width of the strap. Soft, rounded edges and covered seams make the strap super-comfortable out of the water, too. Forerunning, provides feedback on running form (cadence, vertical oscillation and ground contact time). Capable of storing up to 20 hours of heart rate data.

Extensive Running Dynamics

When running, this pairing allows your compatible wearable to report 6 running dynamics metrics: cadence, stride length, ground contact time, ground contact time balance, vertical oscillation and vertical ratio.
