Canadian teenager Summer McIntosh broke her 3rd World Record in Budapest, swimming a 4:15.48 in the women’s 400 IM. That also broke her own World Junior Record of a 4:21.49 that McIntosh swam in 2022.
McIntosh broke the old World Record of a 4:18.94 set by Spain’s Mireia Belmonte Garcia in 2017. This was the 2nd event of the week in which McIntosh broke a record previously held by Belmonte as McIntosh also swam to a World Record in the 200 fly. She also swam a World Record in the 400 free earlier this week.
Split Comparison
| McIntosh | Belmonte | |||
| 50 | 26.88 | 26.88 | 27.99 | 27.99 |
| 100 | 57.23 | 30.35 | 59.38 | 31.39 |
| 150 | 1:29.60 | 32.37 | 1:33.37 | 33.99 |
| 200 | 2:00.97 | 31.37 | 2:06.46 | 33.09 |
| 250 | 2:38.09 | 37.12 | 2:42.27 | 35.81 |
| 300 | 3:16.34 | 38.25 | 3:19.24 | 36.97 |
| 350 | 3:46.94 | 30.6 | 3:49.63 | 30.39 |
| 400 | 4:15.48 | 28.54 | 4:18.94 | 29.31 |
McIntosh was out fast as she was already two seconds under World Record pace at the end of the fly leg. She grew her lead on the backstroke leg. Belmonte was slightly faster on the breaststroke leg but McIntosh was already far enough ahead of record pace that it did not matter.
McIntosh continues her success after winning three individual gold medals this summer at the 2024 Paris Olympics.
Katie Grimes Breaks American Record
Summer McIntosh wasn’t the only record setter in the 400 IM final. American Katie Grimes was under World Record pace through the 200 meter mark, and fell off, placing 2nd to McIntosh in 4:20.14. This time might not have been the World Record, but it was a new American Record by almost exactly 4 seconds.
The previous record was 4:24.15 which was set by Melanie Margalis at an ISL meet in 2019. Grimes was just off this mark in prelims coming in at 4:24.74, but she easily went under tonight.
Split Comparison
| Katie Grimes | Melanie Margalis | |
| New Record: 4:20.14 | Old Record: 4:24.15 | |
| Fly | 58.59 | 1:01.10 |
| Back | 1:04.58 | 1:09.77 |
| Breast | 1:16.77 | 1:12.34 |
| Free | 1:00.20 | 1:01.14 |
Grimes was faster on every split, except the breaststroke where she was almost 4 and a half seconds back, but she had more than enough cushion to make up for that.
It will be extremely interesting to see how Summer fares today in the 200 backstroke. So nice to see her trying a new event. I think she will do quite well♡.
In a thread last night I posted that McIntosh needed to go 6 seconds under the pace and then take her chances.
Instead it was 5.48 seconds. I was a bit annoyed at the tentative beginning but still a good stepping stone race for her, like a starter home.
Tentative beginning?
She’s also inspiring the next gen. At the Ontario JR Champs this wkd a young BC swimmer has just broken 3 of Summers 🍁 12&u NAT records: 200 fly, 200IM, 400IM !!
200 breaststroke, not butterfly. She broke two of McIntosh’s records, 2 and 4 IM, and it’s because her breastroke is insanely good, not fly
Summer 200 Fly NAG 2:18.03 Nov 2018
This weekend this young talent went 2:17.26 at Ontario’s.
So she’s insanely good at multi strokes, but yes breast is her best as she’s also re-broken her 100/200 Brst down to 1:08.75 and 2:25.75.
So…yes 3 of Summer’s records in “Summer’s” best events, + 2 additional Breast = 5…. so far!
What is her name?
You’re Rockin’ again girl! Canada 🇨🇦 loves you!
Didn’t Julia Smit swim a 4:21.0 and set a WR in the 400IM in 2009?
yes, but it wasn’t recognised as an american record: https://swimswam.com/suit-gap-records-the-asterisk-on-the-american-records-book/
way better memory than me, that was such a weird year
Are you missing someone from the record books?
American Record (SCM)
Women’s 400 meter individual medley
Smit, Julia – 4:21.04 (Dec 18, 2009)
That swim doesn’t count as an American Record because USA swimming has already outlawed the suits before world aquatics did.
I nominate my prediction for longest standing WJR record
Too bad McIntosh couldn’t have another LC meet to take the 200 FL sub 2:03…
I think the toughest WJRs from McIntosh are (in order)
4:24.38 (400 IM L)
2:03.03 (200 FL L)
4:15.48 (400 IM S)
3:56.08 (400 FR L)
1:59.32 (200 FL S)
400 free LC at the bottom. The big 400 fr stars trend very young (Titmus being the big exception)
Katie Grimes broke the 5 year old American record by 4 seconds. Summer and Katie were flying!
