FĒNIX 7 SERIES Owner’s Manual

Running Dynamics

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.

Cadence: 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.

Training with Running Dynamics

Before you can view running dynamics, you must put on a running dynamics accessory, such as the HRM-Pro accessory, and pair it with your device (Pairing Your Wireless Sensors).

  1. Hold MENU.
  2. Select Activities & Apps.
  3. Select an activity.
  4. Select the activity settings.
  5. Select Data Screens > Add New.
  6. Select a running dynamics data screen.

NOTE: The running dynamics screens are not available for all activities.

  1. Go for a run (Starting an Activity).
  2. Select UP or DOWN to open a running dynamics screen to view your metrics.

Tips for Missing Running Dynamics Data

If running dynamics data does not appear, you can try these tips.

  • Make sure you have a running dynamics accessory, such as the HRM-Pro accessory.
  • Accessories with running dynamics have on the front of the module.
  • Pair the running dynamics accessory with your fēnix device again, according to the instructions.
  • If you are using the HRM-Pro accessory, pair it with your fēnix device using ANT+ technology, rather than Bluetooth technology.
  • If the running dynamics data display shows only zeros, make sure the accessory is worn right-side up.

NOTE: Ground contact time and balance appears only while running. It is not calculated while walking.
