Which Events Got Faster From Tokyo And Which Got Slower? Day 1 Analysis

Comments: 10

This morning saw questions on whether or not the Olympic pool in Paris is “slow.” How does every result from today’s action compare to Tokyo, did 4th place get slower in some events?

Overall, finals had a more positive result and got faster this year compared to Tokyo at the top. Prelims was slower in five out of the six events this morning for the top seed while tonight, the top finisher was slower in 3 out of 6 events.

The data has mixed results throughout all of the results. The men’s 400 freestyle had a greater range in the top 8 tonight and was faster at the top but slower at the bottom. The men’s 100 breast was slower top to bottom. The women’s 100 fly was faster top to bottom while the women’s 400 free was slower at the time and faster at the bottom, resulting in a smaller range.

Prelims data saw almost every event get slower at the top. The only event that was faster in Paris this morning was the women’s 4×100 free relay as the Australians posted a 3:31.57. The largest difference in the top seed came in the women’s 400 free as Katie Ledecky was 1.74 seconds slower today than in Tokyo, posting the top times in both prelims sessions.

Although the top times were slower, the times that it took to move onto semifinals and finals did not see as big of a fall off. All six of the times from the morning that it took to move on either got faster or were within less than half of a second of what it took in Tokyo. The men’s 100 breast was the biggest difference as it was 0.32 slower this year than in Tokyo while the women’s 400 free saw the biggest drop of 0.24 seconds.

Looking at all the times today, it all starts to make sense if you subtract about .5 per 100. Gretchen, Lucas, and Pan would have WRs, Aussie women and American men break the relay records. Men’s breastroke would still be on the slow side but not egregious like it is now. The top 4 women’s 400 freestylers were about 2 seconds off what you’d expect.

I would bet there won’t be a single WR this meet. If there is, it will be a truly extraordinary swim.

Comparing to the last Olympics is hardly useful in trying to determine if the pool is slow- that was 3 years ago- compare to world championships 23/24, trials, etc and it’s obvious.

100 breast was egregiously slow. Every other event was maybe slightly slow but nothing too bad

Any theories why breastroke in particular is slower here? Most of the key contenders are all around .7 to 2 seconds off their PBs heading into final.

Maybe there’s a really nasty wave on the way back. The first 50 splits of Peaty/Qin weren’t too bad and on brand with their 57-58 low times but they had pretty slow last 50s

Interesting! And breaststroke vs other strokes generally creates more waves in the pool?

If the issue is that a shallower pool causes more waves, then maybe that’s why? Breaststroke, being the slowest stroke and the most technical, is the most susceptible to disturbance IMO.

What’s also interesting is that it appears to be the middle lanes which are seemingly more impacted by the waves than the outside waves. A number of swimmers today went quicker when they had an outside lane compared to in the middle.

Now watch Martinenghi claim a gold based off this theory!
