  • The Garmin HRM4-Run Premium HRM4 w/Running Dynamics heart rate monitor provides the most advanced running metrics to high-end Garmin Forerunner® running watches. The strap is seamlessly comfortable and easily adjustable while the module is small, lightweight and fits entirely within the width strap.  

    How It Works

    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.  

    This real-time data can help athletes take their performance to the next level by showing them where they can improve their running form.
