Pair your compatible Garmin device with the HRM-Run to get not only heart rate information but also real-time feedback about your running form.
HRM-Run has an accelerometer in the module that measures torso movement in order to calculate 3 different 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 you spend on the ground while running. It is measured in milliseconds
¹HRM-Run is compatible with several fitness products and can display heart rate data when paired. Running dynamics features are available only on the Forerunner 620, fenix 2, fenix 2 Special Edition, fenix 3, fenix 3 Sapphire, epix and Forerunner 920XT.
