Once paired with your compatible smartwatch, just clip it to the back and center of your waistband and start your run. View and analyze important running metrics, such as your cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These biomechanical measurements can help you understand your running form, so you can perform better on race day.
