Garmin HRM-Run

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 — the 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 — the ratio of vertical oscillation to stride length (displays a percentage); a lower number typically indicates the 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.   Heart Rate Monitor - Run™ Features: Runner Heart Beat Monitor Specifically Designed for Runner 2.4 GHz ANT Wireless Communication Small & Light for Use Easy Adjustable Strap- Makes it Comfortable to Wear Cadence- Number of Steps per Minute Vertical Oscillation- Measures Degree of 'Bounce' in Running Motion- Displays Vertical Motion of Torso- Steps are Measured in Centi-Meteres Ground Contact Time- Amount of Time on Each Step Spend on Ground- Measured in Milliseconds Ground Contact Time Balance- Displays Left/Right Balance While Ground Contact (Displays a %) Stride Length- Length of your Stride from 1 Footfall to The Next- Measured in Meters Vertical Ratio- The ratio of Vertical Oscillation to Stride Length (Displays a %) Works with Garmin Models: Fenix: fenix 2, fenix 2 Special Edition, fenix 3, 3 Sapphire HR,  fenix 3 HR, fenix 3 Sapphire, 5, 5 Plus, 5S, 5S Plus, 5X, 5X Plus, 6, 6-Pro and Sapphire, 6S, 6S - Pro and Sapphire, 6x - Pro and Sapphire, 6X-Pro Solar, Chronos D2™: Bravo, Charlie epix™ Edge: 25, 130, 530, 810, 830, 1000, 1030 Descent: Mk1 Forerunner®: 230, 235, 245, 245 Music,630, 645, 645 Music, 735XT, 935, 945 Foretrex®: 601, 701 Ballistic Edition MARQ: Adventurer, Athlete, Aviator, Captain, commander VIRB®: XE, Ultra 30 Aviation In-Cockpit Bundle, Ultra 30, 360 Tactix®: Bravo
