100 m butterfly, men, 25 m pool

What to remember

Joshua Liendo was born in Toronto, and it was in his home city, on October 23, 2025, at a World Cup meet, that he swam the 100 m butterfly in 47.68 s in a 25-metre pool.

The Canadian specialises in freestyle and butterfly. This event has already brought him major results: the Commonwealth title in 2022 and an Olympic silver medal at the 2024 Paris Games. He represented Canada at the 2020 and 2024 Olympics. He was also the first Black Canadian swimmer to win an individual medal at a major international championship, and the first to win an Olympic medal.

The men's 100 m butterfly joined the Olympic programme in 1968, after the women's race, which had been held since 1956. Men and women alike have raced it at the World Aquatics Championships from 1973 on. World records, ratified by World Aquatics, are kept separately for long and short course. For short course, the women's 100 m butterfly record belongs to the American Gretchen Walsh; for long course, the men's record goes to the American Caeleb Dressel.
