If the schedule allows it I would go for both. But if it doesn’t, what event should she focus on? I think I’m leaning more towards 800. Her chances of winning a US title is higher in the 1500m, however her chances at medaling are much higher in the 800m. You have to be sub 3:55 shape to medal in the 1500- For the 800, it requires about a 1:56 which I can see her doing in a fast final at the Olympics. But who knows where her fitness will be at from now until then.
