Didn’t Kelsi Dahlia swim a 54.59 in 2021 ISL?

I loved seeing her reaction at the end, so shocked and humble! What a fantastic swim. Excited to see what she can do in the 50 and 100 free!

Notice no world record line on broadcast. Did NBC not expect any WRs to be threatened?

Some mistakes. She can do 54.8

Mistakes? Where? The last 10m looked rough but that’s just the way it goes sometimes when you’re obliterating WR pace.

It’s interesting how Gretchen (so far) seems to mirror Dressel’s path. Same 3 main events. Junior World champions & NAG holders. After adjusting to college & new coaches took their swimming to the next tier as upperclassmen. Obliterate NCAA records. Then back it up in LC after a period of debate about whether their performances can carry over. Of course, we’ll see if she is able to convert all this to at least an individual gold. But she is showing her level.

And that’s the part where “GWalsh is only a bathtoob swimmer” was so dumb, to me.

We’ve seen plenty of swimmers develop at different rates SCY v LCM. Why wouldn’t one of the most talented ones not eventually ‘figure it out’?

Did make me connect way more with this record tho, I didn’t expect to be ~~moved~~ the way I was

Torri was long on the finish and still 55.7. Gretchen has the kind of shoulder flexibility I haven’t seen since Lars Frolander.
