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 (

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.
Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try these
tips.
• Make sure you have the HRM-Run accessory.
Accessories with running dynamics have on the front of the
module.
• Pair the HRM-Run accessory with your Forerunner 630
device again, according to the instructions.
• If the running dynamics data display shows only zeros, make
sure the heart rate monitor is worn right-side up.
NOTE:
Ground contact time appears only while running. It is
not calculated while walking.
Setting Your Heart Rate Zones
The device uses your user profile information from the initial
setup to determine your default heart rate zones. You can
manually enter heart rate values and set the range for each
zone.

of your heart rate reserve (maximum heart rate minus
resting heart rate).
• Select

Letting the Device Set Your Heart Rate
Zones
The default settings allow the device to detect your maximum
heart rate and set your heart rate zones as a percentage of your
maximum heart rate.
• Verify that your user profile settings are accurate (
).
• Run often with your compatible heart rate monitor.
• Try a few heart rate training plans, available from your
Garmin Connect account.
• View your heart rate trends and time in zones using your
Garmin Connect account.
Physiological Measurements
These physiological measurements require a compatible heart
rate monitor. The measurements are estimates that can help
you track and understand your training runs and race
performances.
NOTE:
The estimates may seem inaccurate at first. The device
requires a few runs to learn about your running performance.
VO2 max.
: VO2 max. is the maximum volume of oxygen (in
milliliters) you can consume per minute per kilogram of body
weight at your maximum performance.
