So, Summer McIntosh broke another World Junior Record tonight at the 2022 World Championships, marking her 2nd WJR of the session. At the beginning of the session, the 15-year-old superstar won her first World title, winning the women’s 200 fly in 2:05.20, which took 0.59 seconds off the WJR she had set yesterday in semifinals.

Canada then elected to have the phenom lead-off their women’s 4×200 free relay tonight, and boy, was that a great decision. Despite being on the lead-off, McIntosh posted one of the fastest splits in the field, coming in at 1:54.79. Not only was the time a massive personal best for McIntosh, but she also broke the World Junior Record of 1:55.11, which was set by Australia’s Mollie O’Callaghan last summer in Tokyo. Additionally, the time by McIntosh was faster than the 1:54.92 it took to win Gold in the individual women’s 200 free last night.

From a splits standpoint, McIntosh swam a fantastic race. Here is a comparison between her splits tonight, and Mollie O’Callaghan’s splits from the previous WJR:

Splits Summer McIntosh – 4×200 Free Relay Finals 2022 World Champs Mollie O’Callaghan – 4×200 Free Relay Prelims – Tokyo 2020 Olympics
50m 27.32 27.25
100m 56.22 (28.90) 56.94 (29.69)
150m 1:25.59 (29.37) 1:26.70 (29.76)
200m 1:54.79 (29.20) 1:55.11 (28.41)
FINAL TIME 1:54.79 1:55.11

The pair actually swam their races rather differently. O’Callaghan is known for her closing speed, while McIntosh pushed the middle 100 hard. McIntosh split 58.27 on the middle 100 tonight, whole O’Callaghan was 59.45 on her swim last summer.

As is the case with all McIntosh’s World Junior Records, we have to note that she’s only 15, and therefore has a ton of time left to lower these marks.

I was inevitable after her 400.

The 4×200 at the Commonwealth games isn’t scheduled with any of her other events. Without the 200 fly double she might even go a 1:54 low next month

There's no doubt that he's tightening up

400 IM still to come. I think Hosszu’s WR is beyond her reach at present, but it would be nice to see the actual WJR, Ye Shiwen’s 4:28.43, go down.


According to, Summer already holds the 400IM record in 04:34.86:


I don’t know what Summer McIntosh’s tapering procedure is and what meet she is focusing at: WC or CWG or booth. So the performance can be quite different at these two meets.
The major difference in schedules for Summer is that at WC the 400FR comes on the first day and 400IM – at the very end. At WCG the 400IM will be right at the beginning of the meet. So if she is equally ready for these two meets that make sense to make a major statement at 400FR at WC (which she did) and to focus on 400IM at CWG.
Or to do both at each meet while you are still under 16 and double tapering… Read more »
