16-Year-Old Summer McIntosh Breaks the World Record in the 400 Free at Canadian Trials

2023 CANADIAN SWIMMING TRIALS

The best rivalry in world swimming just got even better. 16-year-old Summer McIntosh broke the World Record in the women’s 400 meter free on Tuesday, knocking over three-tenths off the old World Record of Australian Ariarne Titmus.

McIntosh swam 3:56.08, which broke Titmus’ record of 3:56.40, set at the 2022 Australian Swimming Championships.

RACE VIDEO:

McIntosh, by consequence, also broke Titmus’ Commonwealth Record, her own Canadian Record, and Katie Ledecky’s World Junior Record.

Former Records:

  • World Record – Ariarne Titmus, Australia, 3:56.40 (2022 Australian Championships)
  • Commonwealth Record – Ariarne Titmus, Australia, 3:56.40 (2022 Australian Championships)
  • Canadian National/Age Group Record – Summer McIntosh, 3:59.32 (2022 Commonwealth Games)
  • World Junior Record – Katie Ledecky, USA, 3:58.37 (2014 Pan Pac Championships)
  • Americas Record – Katie Ledecky, USA, 3:56.46 (2016 Summer Olympics)

While McIntosh has broken several World Junior Records, this swim is her first World Record.

She won a silver medal in this race at the 2022 World Championships, behind Ledecky, to go with World Championships in the 400 IM and 200 fly. She hasn’t swum much of the 400 free since then, however – she posted a 4:08.16 in early February in long course at a US Sectional Championship meet, and a 4:06.68 at the US Open in December.

She did have a massive drop in October in the World Cup in short course meters, though. She swam 3:52.80 in Toronto, which is her career best by five seconds.

McIntosh previously trained under Ben Titley at the Swimming Canada High Performance Group in Canada, with occasional training trips to Florida, but is now training full-time with the Sarasota Sharks in Sarasota, Florida.

McIntosh is scheduled to swim the 200 IM, 200 fly, 400 IM, and 200 free later in the meet.

Splits Comparison:

McIntosh was super-aggressive in the first half of the race. She was already seven-tenths up on the World Record pace at the 100, and by the halfway mark she was more than a second ahead of World Record pace.

She gave a lot of that back on the back-half of the race, but had more-than-enough room to still clear the record.

McIntosh’s first 200 meter split of 1:55.91 would have won a bronze medal at last year’s World Championships.

i can’t even start trying to describe how annoying it is that 99% of the world’s population can’t watch this live/on demand. I would have gladly paid but this stupid CBC, much like it’s American counterparts only allow people in Canada to watch the 1st world record of swimming’s most promising talent. So bad for the fans, so bad for the sports. so idiotic. boooo

I had an inkling that Summer might do something special when I read a comment from Brent Arckey yesterday while being interviewed by a CBC Reporter. Apparently he was asked if Summer might set a record tonight and his response was said with a smile “ with Summer you never know”. Being her coach he obviously knew what she might be capable of and said afterwards that some of the things she does in practice are unbelievable.

Summer, who is usually quite stoic and shows little emotion after each race broke down when talking about her family and the support she has received over the years, and being that it happened in her home town in front of them made… Read more »

Ya know, I heard somewhere that she’s pretty decent at fly and IM too! 🤔

I mean, last year she swam the fastest time in the 400m IM that anyone has swam since 2016, and the third fastest time in history. All indications suggest that she’s improved in her other strokes since then as well. Also, her time at the half-way point in this race would make for a decent relay split in the 4×200.

Amazing swim! Ledecky will always be my Queen though. I hope Summer goes after the 200 fly and breaks a sus WR.

200 free will be her 5th event of the week. Let’s just see how the rest of the week unfolds.

She is not ‘only’ extraordinary, but she is one of those very few swimmers that happen to appear once every 20/40 years. One of those who when swimming makes you think that something amazing is gonna happen, maybe a national record, maybe a WR….

That’s why we are so BLESSED to see someone like her swimming.
Can’t stress this enough :

Summer is the bomb !
