Weeks before the 2022 Beijing Winter Olympics, 15-year-old Kamila Valieva, a figure skater from Russia, tested positive for a banned heart medication. In the past, that would be enough to disqualify an athlete from international competition for some amount of time, but in the case of Valieva, she was allowed to compete in the opening days of the Beijing Olympics. It's unclear why.
This doping revelation was not released until after Valieva had already started competing and had helped her fellow Russian Olympic Committee (ROC) figure skaters win gold in the Beijing Olympics figure skating team event, where Valieva shined. She wowed her fellow competitors and fans all over the world by becoming the first woman to complete a "quad" in competition, an extremely difficult maneuver where she spins four times in the air before landing on one foot.
