As the 2012 Tour De France entered the Alps on Wednesday, France's Thomas Voeckler scaled the Grand Colmbier, one of the most difficult climbs in cycling, to win Stage 10.
He led a five-rider breakaway group, finishing three seconds ahead Italy's Michele Scarponi and seven seconds ahead of third-place Jens Voigt of Germany.
Bradley Wiggins of Belgium still has the overall lead. He withstood attacks from reigning champion Cadel Evans as well as Vincenzo Nibali and Jurgen Van Den Broeck.
The second-place Evans trails Wiggins by 1:53. Wiggins' Team Sky teammate Christopher Froome is 2:07 back in third. Nibali is fourth, 2:23 back.
On Thursday, the riders will embark on a trek from Albertville to La Toussuire that features an uphill finish and two of the toughest climbs in cycling.
