Summer McIntosh Shatters 200m Butterfly World Record

Record-Breaking Performance

Summer McIntosh lowered the 200‑meter butterfly mark at the Canadian Swim Championships in Montreal, finishing in 2:01.65.

Her opening 50 metres covered in 27.45 seconds set the pace, and she accelerated dramatically over the final stretch as the home crowd erupted.

The time eclipsed Liu Zige’s 2:01.81 set in October 2009 in Jinan, China, ending a 14‑year‑old benchmark that had been the last standing record from the supersuit era.

Why the Old Record Still Mattered

When high‑tech bodysuits were banned after 2010, many former marks remained untouched for over a decade.

McIntosh’s victory broke the final surviving world‑record from that period, marking a symbolic milestone for the sport.

Her emotional response underscored how the achievement resonated beyond the pool, striking a chord with swimmers who grew up watching the previous standard.

McIntosh’s Growing Legacy

The 19‑year‑old from Toronto already holds four world‑record swims, adding the 200‑fly title to her repertoire of 200‑ and 400‑meter individual medleys and the 400‑meter freestyle.

She collected Olympic golds in the 200‑ and 400‑meter IM plus a 200‑fly medal at the 2024 Paris Games.

Her eight career world titles include victories at Singapore last year across four distance events.

What Lies Ahead

Next month’s Pan Pacific Championships in Irvine, California, will showcase McIntosh in several disciplines, where she is expected to contend for more gold.

Family talent runs deep; her mother represented Canada in the 1984 Los Angeles Olympics.

Breaking a long‑standing record positions her as a prime contender for future world‑record attempts and reinforces her status as a leader in women’s swimming.
