Garmin FORERUNNER 245 User Manual

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.
Vertical Oscillation and Vertical Ratio Data
The data ranges for vertical oscillation and vertical ratio are slightly different depending on the sensor and
whether it is positioned at the chest (HRM-Tri or HRM-Run accessories) or at the waist (Running Dynamics Pod
accessory).

Tips for Missing Running Dynamics Data
If running dynamics data does not appear, you can try
these tips.
 Make sure you have a running dynamics accessory,
such as the HRM-Run accessory.
Accessories with running dynamics have on the
front of the module.
 Pair the running dynamics accessory with
your Forerunner device again, according to
the instructions.
 If the running dynamics data display shows only
zeros, make sure the accessory is worn right-side
up.
NOTE: Ground contact time and balance
appears only while running. It is not calculated
while walking.
Performance Measurements
These performance measurements are estimates
that can help you track and understand your training
activities and race performances. The measurements
require a few activities using wrist-based heart rate or a
compatible chest heart rate monitor.
These estimates are provided and supported by
Firstbeat. For more information, go to www.garmin.
com/runningscience .
NOTE: The estimates may seem inaccurate at first. The
device requires you to complete a few activities to learn
about your performance.
