Best way to measure distance in an endless pool?
So I have a small above ground pool that I swim in using basically a bungee cord and belt which surprisingly works a LOT better than I expected, but the biggest problem I’m having is basically how to track my workout since basically I can’t count laps… right now I just have a timer set up and do a 5 minute warm up with a 20 min cycle of 1 min sprints 2 min free swim, and end with a 5+ min cool down and by the end I am usually pretty exhausted but i’d like to use some of these swim workouts from online so does anyone know any good way to convert the distances to time or stroke count or vice versa?
