Real-time heart rate transmission via ANT® connectivity (2.4 GHz) . This is NOT a Bluetooth heart rate monitor

HRM-Run provides 6 running dynamics metrics:

Cadence — number of steps per minute

Vertical oscillation — degree of ‘bounce’ in your running motion; displays the vertical motion of your torso, measured in centimeters for each step

Ground contact time — amount of time in each step that you spend on the ground while running; measured in milliseconds

Ground contact time balance — displays the left/right balance of your ground contact time while running (displays a percentage); for example, 53.2 with an arrow pointing left or right

Stride length — length of your stride from 1 footfall to the next; measured in meters

Vertical ratio — ratio of vertical oscillation to stride length (displays a percentage); a lower number typically indicates better running form
