Why we list a instrument metronome? Runners can benefit from using it during road runs. Put it on 90 tempo, step on the beep with left foot, and start your 180 cadence per minute. 

Kindly note that the device is not water proof. Sweat can affect the screen display and normal function. It's important to keep the device dry while running.
