For many runners, ground contact time balance tends to deviate further from 50-50 when running up or down hills. Most running coaches agree that a symmetrical running form is good. Elite runners tend to have quick and balanced strides. You can watch the gauge or data field during your run or view the summary on your Garmin Connect account after your run.

Vertical Oscillation and Vertical Ratio Data The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and whether it is positioned at the chest (HRM-Pro series, HRM-Run™, or HRM-Tri accessories) or at the waist (Running Dynamics Pod accessory).

Ground Contact Time Balance Data
Ground contact time balance measures your running symmetry and appears as a percentage of your total ground
contact time. For example, 51.3% with an arrow pointing left indicates the runner is spending more time on the ground
when on the left foot. If your data screen displays both numbers, for example 48–52, 48% is the left foot and 52% is the
right foot.

Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and whether it
is positioned at the chest (HRM-Pro series, HRM-Run
, or HRM-Tri accessories) or at the waist (Running Dynamics Pod
accessory).
