Notes
This was probably closer to 15 miles - I stopped my watch while we were waiting at a stoplight about 3 miles in and forgot to restart it.. heard it beep about 5 minutes later and figured it was just auto lapping at the mile, but when I heard it beep again 10 seconds later, I looked down and saw it was about to go into sleep mode.. oops! I think that happens at 5 minutes of inactivity.
