PARIS (AP) - Alberto Contador won his third Tour de France on Sunday, heralding the arrival of a new cycling superstar, as seven-time champion Lance Armstrong competed in the race for the last time.
      
Mark Cavendish of Britain led a sprint to win the 20th and final stage - a largely ceremonial 63.7-mile course from Longjumeau to the Champs-Elysees in Paris.

Contador of Spain sealed his third title in four years by holding off a challenge from his main rival, Andy Schleck of Luxembourg, in Saturday's individual time trial.
      
Schleck finished second, 39 seconds back, and Denis Menchov of Russia was third overall.
      
Armstrong finished in 23rd place, 39:20 after Contador, his former teammate and rival.
