Running Dynamics

You can use your compatible MARQ device paired with the
HRM-Pro accessory or other running dynamics accessory
to provide real-time feedback about your running form.
The running dynamics accessory has an accelerometer
that measures torso movement in order to calculate six
running metrics.
Cadence: Cadence is the number of steps per minute. It
displays the total steps (right and left combined).
Vertical oscillation: Vertical oscillation is your bounce
while running. It displays the vertical motion of your
torso, measured in centimeters.
Ground contact time: Ground contact time is the amount
of time in each step that you spend on the ground while
running. It is measured in milliseconds.
NOTE: Ground contact time and balance are not
available while walking.
Ground contact time balance: 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: Stride length is the length of your stride
from one footfall to the next. It is measured in meters.

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.

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

Vertical ratio: Vertical ratio is the ratio of vertical
oscillation to stride length. It displays a percentage. A
lower number typically indicates better running form.

Training with Running Dynamics

Before you can view running dynamics, you must put
on a running dynamics accessory, such as the HRM-Pro
accessory, and pair it with your device
