You can use your compatible fēnix® device paired with the HRM-Pro™ accessory or other running dynamics accessory to provide real-time feedback about your running form.
The running dynamics accessory has an accelerometer that measures torso movement in order to calculate six running metrics. For more information, go to garmin.com/performance-data/running.
Cadence is the number of steps per minute. It displays the 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.
- 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 and balance are not available while walking.
- Ground contact time balance
Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right.
- Stride length
Stride length is the length of your stride from one footfall to the next. It is measured in meters.
- Vertical ratio
Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form.
