Most of the women and girls who competed at the 2021 U.S. Olympic Gymnastics Team Trials in June were there alone. Yes, their parents were in the stands, and their personal coaches were on the floor with them. But with the American field whittled to just 18 athletes, the competitive standard was higher than ever. Each of the gymnasts was the best where they came from, local heroes from towns across America—one from Little Canada, Minnesota, one from Chandler, Arizona, two from Blue Springs, Missouri—and most had gradually left their training partners behind as they jumped the many competitive hurdles on the road to Tokyo.
