Pair your compatible Garmin device with the HRM-Run to get your heart rate and real-time feedback about your running form.¹
HRM-Run has an accelerometer in the module that measures torso movement to calculate 3 running metrics:
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).
Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).
¹Running dynamics features are available only on the Forerunner® 620/920XT and fēnix™ 2. HRM-Run is compatible with several other fitness products but will only display heart rate when paired.
