Dozens of Russian athletes at the 2014 Winter Olympics in Sochi, including at least 15 medal winners, were part of a state-run doping program, meticulously planned for years to ensure dominance at the Games, according to the director of the country’s antidoping laboratory at the time. The director, Grigory Rodchenkov, who ran the laboratory that handled testing for thousands of Olympians, said he developed a three-drug cocktail of banned substances that he mixed with liquor and provided to dozens of Russian athletes, helping to facilitate one of the most elaborate — and successful — doping ploys in sports history.
