Tour de France Winner Alberto Contador Found Guilty of Doping

Cyclist Alberto Contador has been banned from competition for two years and stripped of his 2010 Tour de France victory after being found guilty of using a banned substance during the 2010 race. Contador was originally suspended in 2010 after testing positive for the banned substance clenbuterol, but has been allowed to race during the long appeals process. The Spanish Cycling Federation accepted his appeal and reversed his ban in early 2011, but the World Anti-Doping Agency and International Cycling Union appealed that decision to Court of Arbitration for Sport, who handed down their ruling today. All his results since 2010 will be taken off the books.

The announcement comes just days after the U.S. government dropped its own two-year doping investigation against Lance Armstrong, himself a seven-time winner of the Tour, who has also been embroiled in allegations of drug use. (At least two former teammates have claimed they witnessed him taking banned doping substances.) Luxembourg's Andy Schleck finished second in 2010 and will now become the official winner of that Tour de France.
