Garmin HRM-Run

We like this HR monitor as it makes keeping the band and HRM sensor together quite easy since it's screwed on. The one year battery life? We'll see how it goes. The strap is comfortable thanks to a material that covers the hook attachment. Plays nice with Garmin watches to include bonus metrics.

Garmin Says: The HRM-Run 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.

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.
