50m

Olympic pool distance

Fifty meters, a distance used in swimming and track events.

The 50m freestyle is the shortest Olympic swimming race—one length of an Olympic-sized pool.

In running, a 50m dash tests pure acceleration.

The notation also describes pool length: a 50m pool versus a 25m short-course pool.
