Training with Running Dynamics
Before you can view running dynamics, you must put on an HRM-Pro™, HRM-Run™, or HRM-Tri™ accessory, or the Running Dynamics Pod, and pair it with your device (Pairing Your Wireless Sensors).
If your Forerunner® was packaged with the heart rate monitor, the devices are already paired, and the Forerunner is set to display running dynamics.
