Key Features and Benefits: Running dynamics When used with HRM-Run, 620 measures how much time, during the running motion, your foot is on the ground rather than in flight. Ground contact time is measured in milliseconds. Most running ground contact times are between 160-300 milliseconds. Elite runners typically spend under 200-milliseconds in contact with the ground each step. Running dynamics When used with HRM-Run, cadence records your number of steps per minute. This feature counts total steps (right and left combined). Previous devices used a foot pod to measure foot strike rate. A typical cadence is between 150-200 steps per minute, with 180 steps being the sweet spot. Running dynamics When used with HRM-Run, vertical oscillation shows the degree of 'bounce' in your running motion. Vertical oscillation is measured in centimeters from a fixed point on your body (sensor on the chest mounted HRM-Run monitor). Recovery advisor Recovery advisor is a set of features that estimate how much time you need to recover from your run so you can more easily assess how hard your next one should be.
