Running Dynamics

You can use your compatible epix™ device paired with the HRM‍-‍Run™ accessory to provide real-time feedback about your running form. If your epix device was packaged with the HRM‍-‍Run accessory, the devices are already paired.

The HRM‍-‍Run accessory has an accelerometer in the module that measures torso movement in order to calculate three running metrics: cadence, vertical oscillation, and ground contact time.

NOTE: The HRM‍-‍Run accessory is compatible with several ANT‍+® fitness products and can display heart rate data when paired. The running dynamics features are available only on some Garmin® devices.

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

Vertical oscillation

Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step.

Ground contact time
Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.
NOTE: Ground contact time is not available while walking.
