Yay!!!
20 hours after the world record was broken in the blue ribbon event and this article only sits at 77 comments so far ? Damn..
American homers would have bombarded this comment section if it was a swimmer from Uncle Sam. Would have easily reached 300 comms in less than day.
I think Mollie will have to settle for being one of the greatest 200m swimmers in history… that’s pretty good.
Too early to dismiss anything, but it just goes to show how hard 100/200 split focus is vs pure specialisation.
So few people make it work, and not for that long. At least it is still somewhat doable unlike the equivalent track pairing of 400/800m of which only 2 people in history have pulled off.
I will pay money to see footage of that swim.
Women’s sprinting is just getting faster and the Aussie trials have shown the girls have their work cut out for them .. what truly worries me is that they prefer to hide away and train in Australia and only come out during big meets .. whereas these girls who are swimming fast like Steenbergen and Moesch are out there not afraid to race and race fast .. Mollie O needs to work out her first 50 speed but she’s not doing enough racing to practice her race pace for the big meet.. even Henry Allan needs more race practice as his technical skills need a lot of work too
You would have thought Mollie learnt her lesson after the 100 free final in Paris, before which she had this ‘there’s no way I could lose this’ smirk.
Aussies expecting miracles once they come out of hiding and swimming fast times at the world stage
Was that “smirk” before or after her hands were shaking prior to racing as they do every time she swims at a big meet as she is so nervous. Stop making stuff up. It’s ridiculous.
smiling should be automatic DQ
A bunch did do World Cup last year and China Open this year so not completely true.
Pressure is largely off this year, plenty of time for strategic adjustments to be made addressing shortcomings with certain events.
Geography doesn’t help!
Aussies and Americans kept saying Mollie or Ana but the record will remain European lol
Anna has a good chance to rewrite the record…
first 50 split / total time of the personal best swims of all of the ladies that have been sub 52.1. The mean of the 9 is 48.368%, so she’s like actually right at the middle
Manuel 47.674%
Sjostrom 48.018%
Haughey 48.212%
C1 48.222%
McKeon 48.268%
Steenbergen 48.336%
Moesch 48.479%
Steffen 48.895%
MOC 49.212%
Interesting technique breathing every 4. Sort of combines the gallop with the heads-down-no-breath 50 stroke. Makes a ton of sense for that race.
