BELLEGARDE-SUR-VALSERINE, France — Thomas Voeckler of France led a five-rider breakaway to win the 10th stage of the Tour de France as the race entered the Alps on Wednesday, while Bradley Wiggins retained the overall lead.

The 120.9-mile ride from Macon-sur-Valserine marked a return to racing after Tuesday’s tumultuous rest day in which a Cofidis rider was suspended by his team following his arrest by police in a doping probe.

For the first time in the Tour, the peloton scaled the 10.9 mile Grand Colombier pass — classified as one of the hardest climbs in pro cycling in part for two tough patches with steep, 12 percent gradients.
