She races like a high schooler — antsy, making unnecessary sharp moves and surges. It started with the semi-final where she seemed to be running panicked, jostling to always get to where she thought she needed to be. Be patient! Sure enough, space opened soon after these moves and her moves proved to be pointless. Compared to the confidence in one's fitness displayed by runners like Kipyegon, the difference is stark.
Then in the final today, it seems she has an adolescent mentality of "stay right on the leader, no matter what!" — even if the leader is Tsegay going out at a suicidal pace. I think it's obvious to say that she and Hiltz would have been better served today doing something closer to what Muir did and running a bit more within themselves for the first 600.
St. Pierre is fit, sure, but lots to learn in the ways of racing.
