A swimmer's mile

[SwimTeamSpeedo]

In the USA, many pools, especially older ones, are 75 feet (25 yards) or 150 feet (50 yards). 36 laps is the "accepted" amount of laps for a mile in a 75 foot pool. The actual required distance is 35.2 laps. A 25 meter pool is 82.02 feet. It requires 32.2 laps. The "accepted" distance is 32.

Hope this helps.
