The Garmin Running Dynamics Pod is compatible with the Forerunner 245, 245 Music, 645, 645 Music, 735XT, 945 and Fenix 5 series. It easily clips on to any waistband and is so small and light you won't know you're wearing it. When you've finished it will automatically turn itself off. The pod will expand on the statistics that your watch already shows to give you a much more in-depth view of your running dynamics, including stride length and ground contact time.These biomechanical measurements will help you to improve on your running form and be more energy efficient, helping you perform better on race day. The battery is replaceable and can last up to a year (based on approx 1 hour use a day)FeaturesThe Running Dynamics Pod has an accelerometer in the module that measures torso movement to calculate these 6 running metrics: Cadence is the number of steps per minute. It displays the total steps (right and left combined). Ground contact time balance displays the left/right balance of your ground contact time while running. It displays a percentage. For example, 53.2 with an arrow pointing left or right. Stride length is the length of your stride from 1 footfall to the next. It is measured in meters. Vertical oscillation is your bounce while running. It displays the vertical motion of your torso, measured in centimeters for each step. Vertical ratio is the ratio of vertical oscillation to stride length. It displays a percentage. A lower number typically indicates better running form. Ground contact time is the amount of time in each step that you spend on the ground while running. It is measured in milliseconds.
