Three-time and defending Tour de France champion Alberto Contador has been suspended by cycling’s governing body for testing positive for a banned substance. Contador tested positive for clenbuterol during the Tour on July 21st. That was the second rest day of the event, and the day before Contador finished a stage in the race’s lead. Contador went on to win the Tour by 39 seconds over Andy Schleck. The International Cycling Union (UCI) issued a release saying that the B samples confirmed the positive test. While the concentration of clenbuterol was “very small,” the UCI said Contador was formally and provisionally suspended. Contador claims the positive test stems from contaminated food, blaming it in particular on bad meat.
