Notes
got off the bike at 1.49 miles to adjust the tension on the back that seemed way too easy and the watch stopped and transfered the data to the computer so I started over. I added the 2 distances 1.49 and 19.02 miles to get 20.51 miles.
I'm not sure if its the tension is too hard or what but 20 miles inside seems so much harder than 20 miles outside.
