Train hard, run free
The Garmin running dynamics sensor can be easily attached to the strap of your pants. It measures whether you've improved your running dynamics from yesterday. This allows you to run without having to wear a chest strap. Once you've paired your compatible smartwatch1, you can attach the sensor to the back center of your pants band and start running.
Rate your shape
View and analyze important running data, such as your cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio. These biomechanical measurements allow you to better understand your running shape, so you can perform better on a race day.
This is how it works
The running dynamics sensor contains an accelerometer, which measures movements of the upper body and calculates the following 6 running data:
- Cadence is the number of steps per minute. The total number of steps is displayed (left and right together).
- Ground contact time balance displays the left/right balance of your ground contact time while running. This balance is displayed as a percentage. For example 53.2% with a left or right arrow.
- Step length is the distance between the places where you put your one foot and your other foot. This length is measured in meters.
- Vertical oscillation is the up and down movement during running. It represents the vertical movement of your upper body, measured in centimeters for each step.
- Vertical ratio is the ratio between vertical oscillation and stride length. This balance is displayed as a percentage. A lower ratio usually indicates a better running condition.
- Ground contact time is the amount of time for each step during running where there is contact with the ground. This is measured in milliseconds.
- Dimensions (LxWxD), sensor in clip: 37.6 mm x 23.2 mm x 19.2 mm
