One can assume she is trying to get as much race practice as possible in large meets, The schedule for these events isn't too bad. 200m free Day 1, 1500m free Day 2, 400m IM Day 3, 400m Free Day 4, 800m Day 6. She would only race once in the 800m and 1500m in the evening session. My guess is she swims the 200m free as a test as where she is at, before changing her schedule based on the 1500m.
Freya not swimming the 200m back doesn't surprise me. She said in a podcast that she based her race last year off Katie's last year and wasn't really sure what she was doing. It would have been hard to make the team anyway with Osrin, Shanahan and Harris all competing.
Come Paris, Matt Richards would have a big schedule if he qualifies for 50m free with all the relays he will likely be doing, so I guess it would have always been a matter of picking the 50m free or 100m fly.
Overall, I'm really looking forward to trials and seeing what the swimmers can do.
If James Guy can improve his 200m then the relay world record looks increasingly likely to go.
Angharad Evans in the 100m breast could be important for the medley relay.
Jacob Peters really impressed me at SC Euros last year, so I'm hoping he can break 51 at trials, same with Ollie Morgan (53 in the 100m back)
