Hassan said she didn't realize she veered out and Muir said she did not realize it either...this should pretty much end this thread. The high insight of replay and slow motion can sometimes give an impression that's different from what the athletes' experience in real-time. Btw, I went back and watched a couple of Hassan races and she has veered out before even when there was no one behind her. Veering out actually happens quite a bit when you become completely lactic approaching the finish line. In fact, most athletes who are tieing up, veer to the right as they approach the finish line, which sometimes opens up the inside lane to pass. With that said, Hassan is a bit of an erratic racer, with a long back kick and sharp elbows; I would try to stay away from when competing.
