Running Dynamics
You can use your compatible Forerunner® device paired with the HRM-Run™ accessory to provide real-time feedback about your running form. If your Forerunner 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
-
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.
