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.
Voeckler, the Europcar rider who wore the yellow jersey for 10 days last year, earned his third Tour stage victory in a decade-long career competing in cycling's premier race.
With a few kilometers to go, Voeckler dusted off the breakaway group, beating runner-up Michele Scarponi of Italy by 3 seconds. Jens Voigt of Germany -- at 40, the oldest rider this year -- was third, another 4 seconds slower.
"I really pulled this out with my guts," Voeckler said. "I only knew I'd won with about 5 meters left."
Voeckler said he didn't ride for about 10 of the 20 days immediately preceding the Tour start because of knee pain that still hasn't fully dissipated.
At several points during the stage, Wiggins came under attack from some of his biggest rivals -- but nearly all failed to make up any ground. Italy's Vincenzo Nibali tried to surge ahead in a big descent; Belgium's Jurgen Van Den Broeck attempted to jump ahead on the day's big climb; reigning champion Cadel Evans tried to shake Wiggins near the end -- but to no avail.
"It was pretty straightforward today," said Wiggins, the Team Sky leader. "Fortunately the break went pretty early and we didn't have to go crazy (chasing it) ... it all sort of went to script today, really."
Doping cases past and present have cast a shadow over this Tour. Just days before the Tour, news emerged of an investigation by French state prosecutors into allegations of improper use of a controlled corticoid by Europcar in last year's Tour -- claims the team has vigorously denied.
Voeckler said the stage win "is really special because we had criticism before the Tour, because it really hurt me."
Some fans in Belgium at the start of the Tour on June 30 booed Europcar riders in the wake of the news.
"In a small way, my victory today was an answer to that," Voeckler said.
The stage came a day after the arrest of Cofidis rider Remy Di Gregorio of France at his team's hotel as part of a doping probe in southern Marseille. The team has provisionally suspended him.
Wiggins finished the stage 3:16 behind Voeckler, in 13th place, in a group including most of his rivals in the quest to win the yellow jersey when the Tour ends in Paris on July 22.
With Wiggins under a close escort by his Sky teammates, only Van Den Broeck was able to erase 32 seconds with a surge late in the stage. The Belgian trails Wiggins by 4:48 in eighth place.
Overall, Wiggins leads Evans by 1:53. Wiggins' teammate, Christopher Froome, is 2:07 back in third place. Nibali is fourth, 2:23 back, and Russia's Denis Menchov is fifth, 3:02 behind.
Riders embark Thursday on what Wiggins called the hardest stage of the race this year -- a relatively short 92-mile trek from Albertville to La Toussuire, but with two of the toughest climbs in pro cycling and an uphill finish.
