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.

Select Options > Status > Off.

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.

Select START, and select a running activity.

Select START.
