Turning Off the Wrist-based Heart Rate Monitor
The default value for the Wrist Heart Rate setting is Auto. The
device automatically uses the wrist-based heart rate monitor
unless you pair an ANT+ heart rate monitor to the device.
NOTE: Disabling the wrist-based heart rate monitor also
disables the wrist-based pulse oximeter sensor.

From the heart rate widget, hold UP.

Running Dynamics
You can use the pod with your compatible device to provide
real-time feedback about your running form. The pod has an
accelerometer that measures torso movement in order to
calculate six running metrics.
NOTE: The running dynamics features are available on only
some Garmin devices.
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 for each step.
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.
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.
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 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.

Training with Running Dynamics
Before you can view running dynamics, you must put on the
HRM-Run
™
accessory, HRM-Tri
Dynamics Pod, and pair it with your device
Wireless Sensors, page
If your Forerunner was packaged with the heart rate monitor, the
devices are already paired, and the Forerunner is set to display
running dynamics.
