Running Power
Garmin running power is calculated using measured running dynamics information, user mass, environmental
data, and other sensor data. The power measurement estimates the amount of power a runner applies to the
road surface, and it is displayed in watts. Using running power as a gauge of effort may suit some runners
better than using either pace or heart rate. Running power can be more responsive than heart rate for indicating
the level of effort, and it can account for the uphills, downhills, and wind, which a pace measurement does not
do.
You can customize the running power data fields to view your power output and make adjustments to your
training (Data Fields, page120). You can set up power alerts to be notified when you reach a specified power
zone (Activity Alerts, page34).
Running power zones are similar to cycling power zones. The values for the zones are default values based on
gender, weight, and average ability, and may not match your personal abilities. You can manually adjust your
zones on the watch or using your Garmin Connect account (Setting Your Power Zones, page96).
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.
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 (Pairing Your Wireless Sensors, page79).
1 Hold MENU.
2 Select Activities & Apps.
3 Select an activity.
4 Select the activity settings.
5 Select Data Screens > Add New.
6 Select a running dynamics data screen.
NOTE: The running dynamics screens are not available for all activities.
7 Go for a run (Starting an Activity, page5).
8 Select UP or DOWN to open a running dynamics screen to view your metrics.
