The Olympic trajectory that had Simone Biles set for multiple gold medals has gone from all but certain to unclear, at best. On Wednesday, Biles withdrew from the all-around competition. The defending Olympic gold medalist had qualified first for the final on Thursday, but she pulled out to focus on her mental health. “It’s been really stressful this Olympic Games,” said Biles, who came to Tokyo as arguably the Games' biggest star. “It’s been a long week. It’s been a long Olympic process. It’s been a long year." #simonebiles #usa
