Training with Running Dynamics
Before you can view running dynamics, you must put on the HRM-Run™ accessory and pair it with your device (Pairing ANT+ Sensors). If your fēnix™ 2 device was packaged with the HRM-Run accessory, the devices are already paired.
When you pair an HRM-Run accessory with your device, the running dynamics data page is visible when you are running.
