It's obvious. She's overcooked. There's a reason most people end their seasons after a certain number of carefully planned races - you can't hold a peak forever. She should never have been in the race in Stockholm.
As far as making money and getting to see Europe, I'm sure she can afford to see Europe without having to pay her way by racing. I doubt she made much in appearance fees at the race. I doubt she learned anything. I doubt she made much of an impression on the meet directors. I'm just surprised she was there at all. Salazar usually seems like a very careful planner. Rupp, Farah, Centrowitz, etc don't race nearly as frequently.

Tara, is that you?
