100 m individual medley, men, 25 m pool

What to remember

The 100 m individual medley is swum only in short course, for a simple reason: it takes one 25 m length per stroke, butterfly, backstroke, breaststroke and then freestyle.

In the semifinals of the 2020 International Swimming League, at the Duna Arena in Budapest, American Caeleb Dressel became the first man under 50 seconds. On November 22, 2020, again in Budapest, he improved that mark to 49.28 s.

Caeleb Dressel is best known for sprint freestyle and butterfly. At the Tokyo 2020 Olympics he won five gold medals, including the individual 50 m and 100 m freestyle and 100 m butterfly titles, becoming the fifth American since 1970 to win five golds at a single Games. The 100 m individual medley itself has been raced at the short course World Championships since 1999.
