Summer McIntosh set three long-course world records in five days at the Canadian Swimming Trials in Victoria, British Columbia, Swimming World Magazine reported, closing the meet with a 400m individual medley world record. The 18-year-old from Toronto completed the third record on Wednesday night at Saanich Commonwealth Place.
Three World Records in Five Days
McIntosh opened with the 400m freestyle on the weekend, touching in 3:54.18 to shave more than a second off Ariarne Titmus’s world mark, according to Swimming World Magazine. On Monday she won the 200m individual medley in 2:05.70, breaking Katinka Hosszu’s 2015 record by 0.42 seconds, and on Wednesday night she took the 400m individual medley in 4:23.65, lowering her own world record by 0.73 seconds. Her closest rival in the 400m individual medley finished 12 seconds behind.
ABC News reported that the 400m individual medley record she lowered was her own, set at the 2024 Canadian Olympic trials, that she had not previously held the 400m freestyle record, and that Ariarne Titmus had held that mark since July 2023.
The Company She Keeps
Swimming World Magazine reported that McIntosh is the first swimmer since Michael Phelps in 2008 to set three long-course world records at a single meet, and among women the first since Shane Gould at the 1972 Olympics. She becomes the seventh swimmer to hold three or more long-course world records at once, adding the 400m freestyle and 200m individual medley to the 400m individual medley record she already held. The list includes Mark Spitz, Shane Gould, Ian Thorpe, Michael Phelps, Katie Ledecky and Sarah Sjostrom. Swimming World Magazine notes that Phelps set four world records at the 2008 Beijing Olympics.
Close in Two More Events
McIntosh also set Canadian records in the 800m freestyle and the 200m butterfly, both close to long-standing world marks. Her 800m freestyle time of 8:05.07 was the third-fastest women’s 800m freestyle swim in history and within a second of Katie Ledecky’s world record, set last month at Fort Lauderdale, ABC News and Swimming World Magazine reported.
In the 200m butterfly she recorded 2:02.26, about three tenths of a second off Liu Zige’s 2009 mark, Swimming World Magazine reported. She scratched the 200m freestyle.
In Her Words
McIntosh said of the 400m freestyle record, in comments reported by ABC News and the Western Advocate: “It’s been one of those records that’s always been in my mind since trials two years ago.” She added: “I’ve been knocking on the door on this one. I’ve just tried to chip away, chip away at it. To finally do it, it’s kind of like, ‘Wow, I’ve finally got that done.'”
Of the 200m individual medley, she said: “It’s awesome and 200 IM I think is my main race out of my top five, six races where I really have to execute perfectly.” She continued: “There’s no room for mistakes and it’s kind of a sprint event for me.”
“Overall, I’m really happy with that and it gives me a lot of confidence heading into Singapore,” she said. In an Instagram post after the meet, she wrote: “What a week Victoria! Had so much fun in the pool this week.”
What’s Next
McIntosh is scheduled to compete in five events at the World Aquatics Championships in Singapore in July and August, the Western Advocate reported.
