'Serious failings' in Rio Olympics anti-doping programme: WADA

The anti-doping programme at the 2016 Rio Olympics included "some impressive advances" but was also marred by "a number of serious failings", according to a report released on Thursday by the World Anti-Doping Agency (WADA). In a 55-page report by its Independent Observer team, WADA said several athletes earmarked for testing in Rio "simply could not be found" while there was "little or no in-competition blood testing in many high-risk sports" at the Games.
