My Garmin Coach Plan Workout Does Not Automatically End on My Device

Every Garmin Coach workout has a cool down step at the end. The cool down begins as soon as the tough part of the workout is over. This cool down is good for your body, and it gives you a buffer at the end of your workout. When you're done cooling down, select the Lap button on your device and hear the finishing tone that signals the end of your workout. Alternatively, you could select the End button and no tone will sound.
