400 m individual medley, men, 25 m pool

What to remember

Las Vegas, December 2019: at an International Swimming League meet, Japan's Daiya Seto swam the short course 400 m individual medley in 3 min 54.81 s, on the 20th of the month.

The 400 m individual medley demands command of all four strokes, and Seto is precisely a medley specialist, also strong in butterfly, breaststroke and freestyle. Over this distance his record is deep: short course world champion in 2012, 2014, 2016, 2018, 2021 and 2022, he also won the long course world title in 2013, 2015 and 2019. He also held the short course 200 m butterfly world record.

The event has been on the Olympic program since 1964, for men and women alike. It has been swum at the World Championships since 1973 and at the short course World Championships since their first edition, in 1993.
