Flipping Schleck, Andy or Frank in pole position
Frank Schleck moved up to second in the Overall Yellow Jersey Standings and William Hill make him 5/1 to win the big prize. His brother, Andy, is the 6/5 favourite as Alberto Contador, the pre race favourite, slipped further behind in the overall rankings.
With the Schleck brothers in such commanding positions, Hills go 9/1 about the two brothers finishing first and second in any order.
"Having been trumped by Contador last year, the Schleck brothers look to be in a fine position to grab the top prize this year," said Hill's spokesman Joe Crilly.
Mark Cavendish retains favouritism for the Green Jersey, offered at 1/2 ahead of 13/5 Philippe Gilbert.
