MONTREAL — Summer McIntosh broke the longest-standing individual women’s swimming world record Sunday night, finishing the 200-meter butterfly in 2 minutes, 1.65 seconds at the Canadian trials.

The 19-year-old McIntosh broke the mark of 2:01.81 set by China’s Liu Zige in 2009, during what’s known as the super-suit era.

A three-time champion at the 2004 Paris Olympics, McIntosh slammed her fists into the water in celebration while smiling ear-to-ear as the crowd erupted inside the Olympic pool.

McIntosh has long targeted the record, coming within 0.18 seconds with a time of 2:01.99 last year in the world championships.

“As you can see my emotions, this is the absolute world [to me],” McIntosh said after the race. “Growing up this is the one world record I thought I would never break and to do it tonight is really special in front of a home crowd.

“It ​means the absolute world and I’m in shock right now.”

The race Sunday was the first opportunity for many Canadian fans to see McIntosh compete since her high-profile move to train in Austin, Texas, under Bob Bowman, the coach who guided Michael Phelps to a record 23 Olympic gold medals.

McIntosh will compete in the 400 IM on Monday, the 400 free Tuesday and the 200 IM on Wednesday ahead of the Pan Pacific Championships in Irvine, California.
