Wiggins Leads Tour de France Betting

William Hill and other bookmakers are tightening odds on British cyclist Bradley Wiggins defeating all comers and claiming the Tour de France - the sports' biggest annual event - just weeks ahead of the 2012 London Olympics.

William Hill Online is quoting 1/3 odds on Bradley Wiggins winning the Tour de France outright, after he traversed the first mountains stage unscathed. Reigning champ Cadel Evans is 4/1, Chris Froome is 7/1, and Vincenzo Nibali is 16/1. Wiggins is 2/5 to wear the yellow leader's jersey all the way to the finish line in Paris.

In the King of the Mountains classification, Thomas Voeckler has risen to 17/10 favourite after conquering Wednesday's race. He is followed by Pierre Rolland, 5/1, Chris Anker Sorensen, 7/1, Chris Froome pops up once again at 8/1, Sandy Casar is also 8/1, and Thibault Pinot 11/1.
