2025 Canadian Swimming Trials

Women’s 400 Freestyle – Finals

• World Record: 3:55.38 — Ariarne Titmus, Australia (2023)
• Canadian Record: 3:56.08 — Summer McIntosh (2023)
• World Aquatics ‘A’ Standard: 4:10.23

Summer McIntosh made headlines at the Canadian Swimming Trials by breaking Ariarne Titmus’s world record in the 400 freestyle. McIntosh swam an impressive 3:54.18, surpassing her own Canadian record by nearly two seconds.

It’s worth noting that McIntosh is not just a rising star; she won silver behind Titmus at the Paris Olympics last summer. While Katie Ledecky has returned to strong form, McIntosh is now favored to excel at the upcoming World Championships in Singapore.

What stood out in this race was McIntosh’s pacing. Previously, she shot out fast but faded at the end. This time, she was slightly slower at the start but finished strong, recording a remarkable 1:57.76 in the final stretch. This not only showcases her improved strategy but also sets her apart from her competitors.

After her record-setting swim, McIntosh expressed her confidence in her training. “I felt strong throughout the race,” she said. “I didn’t expect to beat the world record, but I could sense the energy from the crowd pushing me forward.”

McIntosh is focusing on the upcoming World Championships. Recently, she trained in France with the CN d’Antibes team under coach Fred Vergnoux. She plans to join Bob Bowman’s group in Texas after the meet in August.

This is the second world record McIntosh has set this season. She previously broke the record at the Short Course World Championships, solidifying her reputation as one of the fastest swimmers in the world.

It’s clear that Summer McIntosh is not only making waves in Canadian swimming but also on a global scale. Her journey is inspiring, and she has a bright future ahead.
