Garmin HRM-Run Heart Rate Monitor

Designed to be paired with the Garmin Forerunner 620, Forerunner 920XT, and the fenix 2, the HRM-Run is Garmin’s most advanced heart rate monitor. In addition to measuring heart rate, the HRM-Run also houses an accelerometer which tracks cadence, vertical oscillation, and ground contact time – which Garmin calls Running Dynamics.

  1. Cadence — the number of steps per minute. It displays the total steps (right and left combined).
  2. Vertical oscillation — the bounce in your running motion. It displays the vertical motion of your torso (measured in centimeters).
  3. Ground contact time — the amount of time in each step that your foot spends on the ground while running (measured in milliseconds).

While the HRM-Run only tracks Running Dynamics for the watches listed above, it will work as a stand-alone heart rate monitor for other units.
