That 400 IM world record, held by Katinka Hosszu at 4:26.46, sits in the distance, two seconds better than any swimmer in history, and McIntosh is third all-time at 4:28.61. Is 3:55 in the cards, possibly as soon as this summer’s World Championships in Fukuoka, Japan? How about the 200 free, where her world junior record of 1:54.13 ranks eighth all-time. Somehow, McIntosh has out-paced even the most ambitious expectations for her potential accomplishments in the pool. [a time of 3:56.06 Tuesday evening at the Canadian Swimming Trials](https://www.swimmingworldmagazine.com/news/flash-summer-mcintosh-takes-down-400-freestyle-world-record-with-356-06/), McIntosh is now the fastest swimmer ever, better than even the legendary performances of her predecessors to hold the No. Even McIntosh recognized the gravity of what she had pulled off. At both meets, her lone silver came in the 400 free, when she finished just over a second behind Ledecky at Worlds and then Titmus at the Commonwealth Games. Out in 1:55.91 at the 200-meter mark, more than a second faster than Titmus in her world-record swim last year. In the end, Summer McIntosh fell behind China’s Li Bingjie for the last spot on the podium, but the swimming world was left anticipating —marveling, even — what this teenager could become. This was the sort of record that had the potential to stand the test of time.
