Defending champion Alberto Contador and last year’s runner-up Andy Schleck renewed their rivalry as riders started the Tour de France on Saturday. The mostly flat first stage takes riders over 119 miles from La Barre-de-Monts to Mont des Alouettes in the Vendee region of western France. Three-time champion Contador beat Schleck by just 39 seconds last year. The 2,131-mile Tour ends on July 24 at the Champs-Elysees.
