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.
she’s been on the up, up and up
We are a few hundredths away from having no more Sjostrom records.
Which is crazy because many said some of her WRs were unbreakable.
Amazing. Is this more evidence that it is best to drop the 200 for 50/100 speed? I’m not sure if Steenbergen is still targeting the 200.
she still does the 200im
And is the European record holder in the short course version of that event. This isn’t someone with a super narrow 50/100 training focus. Coleman did a podcast with her earlier this year and they touch on some interesting pieces with her training. Really different approach during certain periodized blocks and others where she’s putting in bigger volume.
Good question, if we compare with Sarah, she kept the 200 Free as a part of her championship line up through 2019 Worlds (3rd) at which point she was 26 – which happens to be the same age the Marrit is now.
Both Marrit and Siobhan straight off a two week camp at BEST Centre in Mallorca, Spain….something in the water?
Mark Spitz World Record 51.22, 1972 Olympics.
54.27 100 fly! Getting closer.
Ha! Wow.
I’m old enough to remember Spitzmania.
