Common questions

How many laps is a mile in swimming?

In a 25-yard pool, a mile (1,650 yards in swim terms) is 66 lengths, or 33 there-and-back laps. In a 25 m pool a 1,500 m swim is 60 lengths.

What is the difference between SCY, SCM, and LCM?

Short-course yards uses a 25-yard pool, short-course meters a 25 m pool, and long-course meters a 50 m Olympic pool. Times are slightly faster in shorter pools because of more turns.
