Input: Question: Where was the racer who replaced Lance Armstrong on the podium born? Passage:2007 winner Alberto Contador won the race by a margin of 4′11″, having won both a mountain and time trial stage. His team also took the team classification. and supplied the initial third-place finisher, Lance Armstrong. Armstrong's achievement was later voided by the UCI in October 2012 following his non-dispute of a doping accusation by USADA, and fourth place Bradley Wiggins was promoted to the podium. Andy Schleck, second overall, won the young riders' competition as he had the previous year. Franco Pellizotti originally won the polka dot jersey as the King of the Mountains, but had that result (along with all his 2009 results) stripped by the Court of Arbitration for Sport in 2011 due to his irregular values in the UCI's biological passport program detected in May 2010. and the King of the Mountains title was retroactively awarded to Egoi Martínez. Mark Cavendish won six stages, including the final stage on the Champs-Élysées, but was beaten in the points classification by Thor Hushovd, who consequently won the green jersey.
