Seven-time Tour de France winner Lance Armstrong awaits the start of the 2010 Cape Argus Cycle Tour in Cape Town in this March 14, 2010 file photo. The U.S. Anti-Doping Agency brought formal doping charges against former cyclist Armstrong in an action that could cost him his seven Tour de France titles, according to a letter sent to Armstrong and several others June 12, 2012. As a result of the formal charges, Armstrong has been immediately banned from competition in triathlons.
