200 m butterfly, women

What to remember

The 2026 Canadian Trials were held in Montreal, and that is where Summer McIntosh swam the 200 m butterfly in 2 min 01.65 s, on July 5. Hungary's Kristóf Milák holds the men's long course record, while McIntosh also owns the women's short course mark.

The 200 metres butterfly takes four lengths of a long course pool. The men's event arrived at the Olympic Games in 1956 and the women's at the 1968 Games. Both have been contested at the World Aquatics Championships since the inaugural championships in 1973.

The Canadian won the Olympic title over this distance, as Léon Marchand did for the men, and she also took the long course world title. She is a three-time Olympic champion, an eight-time world champion and a two-time Commonwealth Games gold medallist. Equally strong in medley and freestyle, she holds four long course world records in all.
