I want to start doing sprints but I do not have a track available to me. I do have a Garmin GPS watch that measures distance, but it is a bit delayed and I don't know if it measures finely enough to get to-the-meter distances.
Do any of you do sprints on a road or paved surface that has no distance measurements? If so, how?
(And, yes, I know I can do it by time rather than distance, but I have a feeling that I will either over- or under-exert myself by doing it this way.)
