Tips for Missing Running Dynamics Data

This topic provides tips for using a compatible running dynamics accessory. If the accessory is not connected to your watch, the watch automatically switches to wrist-based running dynamics.

  • Make sure you have a running dynamics accessory, such as the HRM-Pro™ series accessory.

    Accessories with running dynamics have Running man on the front of the module.

  • Pair the running dynamics accessory with your watch again, according to the instructions.
  • If you are using the HRM-Pro series accessory, pair it with your watch 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.
    Remember: Ground contact time balance is not calculated with wrist-based running dynamics.
