). After you turn on the run/walk intervals, it is used each time
you go for a run until you turn it off or enable a different run mode.
Training Indoors
You can turn off GPS when you are training indoors or to save battery life. When running or walking 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.
When cycling with GPS turned off, speed and distance data are not available unless you have an optional
sensor that sends speed and distance data to the device, such as a speed or cadence sensor.
1 From the watch face, select START.
2 Select an activity.
3 Select Options > GPS > Off.
NOTE: If you select an activity that is typically done indoors, GPS is automatically turned off.
