How many laps in an olympic size swimming pool equal a mile?
In a 50 meter pool, one mile would be 16 laps (32 lengths).
I, being a Water Safety Survival Instructor Trainer, would swim 4.5 laps if it was a timed event. Because 9 lengths are going to be a little less than 8 yards to short. 5 laps giving you 10 lengths will put you swimming 546.81 yards. So that is what this JARHEAD would advise. An Olympic size pool is 50m (54.68 yards) long so 9.14 laps would equal 500yards.
