The International Olympic Committee’s decision on Monday to allow a Russian figure skating star to continue competing in Beijing despite a failed doping test did not sit right with another top athlete who missed competing in the Olympics for a similar reason: the American sprinter Sha’Carri Richardson.
Richardson, 21, who had been favored to win a medal in the women’s 100 meters, lost her spot on the U.S. team for the 2020 Summer Games in Tokyo after she tested positive for marijuana.
The Russian skater, Kamila Valieva, a 15-year-old whose flawless performance helped lift her country to a gold medal in the team competition last week, tested positive before the Beijing Games for trimetazidine, a banned heart medication that can increase endurance.
