Walsh was out under record pace touching in a 9.80 at the 25 mark. That is also her fastest first 25 in any swim ever including the first 25 of her 50 free where she flips to her feet.
Walsh now holds the eight fastest 100 butterfly times of all-time. No other woman has been sub-48 seconds and Walsh now has gotten under the 47-second mark.

46.97 would have won at men’s ncaas as recently as 1994. It would have qualified for men’s ncaas as recently as 2008. It would have won men’s d3 as recently as 2018, her freshman year of high school.
For context, as ridiculous as this swim is, it’s 3.08% better than Kate Douglass.
Dressel’s 17.63 was 4.55% better than the second best ever by Cesar Cielo
Let that sink in
comparing to 2nd fastest is definitely an easily digestible heuristic, but definitely not the end all be all especially given that it’ll be subject to more variance than comparing to other marks. There’s been a lot of “star power” in the NCAA 100 fly in the several years, much more than in the several years leading up to 2018 in the men’s 50 free
That would have medaled at Winter Juniors East for BOYS. Tied for 3rd with Max Buff.
How do we compare this to Caleb’s 100 fly? More ridiculous?
This swim easily qualifies for the 100 free A-final (would’ve finished 4th in finals last year). If you look at the men’s times from last year, it took a 41.3 to qualify for the A-final and 4th/5th were 40.61 and 40.66
I don’t know how accurate of a comparison that is, but the fact that this could convert to a 40 high/41 men’s 100 fly by this metric is ridiculous
If you use the 2018 numbers instead (“swimflation adjusted”), it took 41.82 to qualify for the A-final and a 41.51 to place 4th, so even conservatively, this swim is solidly like a 41 mid men’s time?
Caeleb himself would’ve been 27th in prelims of the 100 free in 2018; for comparison, Kate Douglass and Maggie MacNeil would’ve been 31st and 33rd in 2023
Way more ridiculous than Dressel’s. She has a bigger margin between her and the second fastest ever, and the pedigree of #2-4 (Douglass, MacNeil, Huske) on the all time list behind her is unreal. That trio is a full .5 ahead of the fifth fastest woman ever. But their swims look pedestrian next to Gretchen.
Greatest. SCY swimmer. Of all time.
This swim puts Gretchen at 3.08% faster than KD
Caeleb’s 50 free was 4.55% faster than Cielo
She’s definitely the greatest short course sprinters in meters and yards.
Australia is silent….. just how we like them.
no Australian is denying how great she is or will continue to be but like everywhere else outside of America we don’t care what times people do in yards. She’s the WR holder and greatest 100 flyer in both SCM and LCM you know real swimming distances that the rest of the world care about yards outside your trigger happy country 🤣
Someone’s angry…
No anger at all, if you read my response I acknowledge how good of a swimmer she is and she’s likely only going to get quicker all I said is that people outside of America generally don’t care about yards which is true considering the rest of the world swims metres. If NCAA were in metres it’d likely receive more international attention however I know that’s extremely difficult to make possible due to the high number of ext only pools in the states
THIS.
I love watching GW swim, but yards times mean nothing to me.
GW just beat the Olympic champion by nearly 2 seconds! Holy smoke!!!
Yep that was my takeaway.
RIDICULOUS
Maxine Parker and Gabi Albiero in the 50y free prelims tied for 7th in 21.63. Which is, as far as I’m aware, the fastest time it has ever taken to make the “A” final in the 50y free.
Gretchen Walsh’s 50y fly split? 21.61.
