Training Indoors
The device includes indoor activity profiles for running, cycling, and swimming. You can turn off GPS when you are training indoors or to save battery life.

When running with GPS turned off, speed and distance are calculated using the accelerometer in the device. The accelerometer is self-calibrating. The accuracy of the speed and distance data improves after a few outdoor runs using GPS.
