Hi I recently started running about 6 months ago and a week ago I decided to buy a Garmin watch to track my mileage; the same one my friend has in our running group. Anyways i got it and it worked great until today. I went to the gym this morning and hopped on threadmill for a 2 mile run. Only I could not tell how far I was going because my watch said 0 miles still after a minute. I checked the satellites and i was connected. What's wrong with my watch? Thanks for any help!
