I would choose either Hoare or Wightman. Ollie has to be torn up over his failure to medal at worlds, so I see his race going one of two ways.
1- He is seeking revenge and runs a time close to the world best
2- He gets in his own head because he has not felt great at the last two 1500 races
On the other hand, I see Wightman going into this race more confident and he has a chance of winning if it turns out to be an honestly paced race.
IMO, the Kenyans will not be likely to win. They always seem to lead from the front, and that has not been working out like it did during the 2021 season.
Bottom line- Wightman has got to be the favorite, but I would not be surprised to see Hoare on top of the podium.
