Saxo Bank-Sungard rider Alberto Contador leaves the team bus before the start of the first stage of the Challenge Mallorca cycling tour in Palma de Mallorca on the Spanish Balearic island on Sunday. Contador was banned from the sport for two years and all his results since Jan 25, 2011 were erased after he tested positive for the banned performance-enhancing drug clenbuterol. Among the events Contador was stripped of are victories in the 2010 Tour de France and 2011 Giro d'Italia. Enrique Calvo / Reuters
