Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try
these tips.
• Make sure you have a running dynamics accessory,
such as the HRM-Tri accessory.
Accessories with running dynamics have
on the
front of the module.
• Pair the running dynamics accessory with your f
ē
nix
device again, according to the instructions.
• If the running dynamics data display shows only
zeros, make sure the accessory is worn right-side up.
NOTE:
Ground contact time and balance appears
only while running. It is not calculated while
walking.
Performance Measurements
These performance measurements require a few
activities using wrist-based heart rate or a compatible
chest heart rate monitor. The measurements are
estimates that can help you track and understand your
training activities and race performances.
These estimates are provided and supported by
Firstbeat.
Color Gauges and Running Dynamics Data
The running dynamics screens display a color gauge for the primary metric. You can display cadence, vertical
oscillation, ground contact time, ground contact time balance, or vertical ratio as the primary metric. The color
gauge shows you how your running dynamics data compare to those of other runners. The color zones are based
on percentiles.
Garmin has researched many runners of all different levels. The data values in the red or orange zones are typical
for less experienced or slower runners. The data values in the green, blue, or purple zones are typical for more
experienced or faster runners. More experienced runners tend to exhibit shorter ground contact times, lower
vertical oscillation, lower vertical ratio, and higher cadence than less experienced runners. However, taller runners
typically have slightly slower cadences, longer strides, and slightly higher vertical oscillation. Vertical ratio is your
vertical oscillation divided by stride length. It is not correlated with height.
NOTE:
The color gauge for ground contact time balance is different

running dynamics data, you can search reputable running publications and websites.

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.

While developing and testing running dynamics, the Garmin team found correlations between injuries and greater
imbalances with certain runners. 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 color gauge or data field during your run or view the summary on your Garmin Connect
account after your run. As with the other running dynamics data, ground contact time balance is a quantitative
measurement to help you learn about your running form.
