Amazing swim. Congrats. Amazing pool as well.
Exciting time for the sport, but also kinda frustrating because usually I expect world records to most fall at championship meets, and now they seem just fall at any in season meet so it’s so much more work now to watch meets live.
This is amazing! Wow, women’s sprinting just suddenly became so intense, with such a deep field. This is so fun to watch.
That should be corrected to the top 10 performers. Not a list of the top 10 performances.
Sjostrom deadass gonna lose all of her wrs in a span of like 10 weeks
Probably, but shows how great this current era of women’s sprinting is. Some of those records had stood for so long
So happy for her! I knew she would break it. What a swim.
I thought she might break it after swimming faster in the 200 than in May, but I didn’t think it would actually happen.
Shed go real fast if decided to go to American University like Auburm!
This was funny only for the first 25 times.
Just got back from my walk. What was only funny the first 25 times?
😂
That’s good.
I seriously was out walking, but now that my walking has become “a thing”, thanks to SN, Bobetc, and you, I shall “walk” lots in these comments now.
