Along the the Tour of Switzerland, the newly named Critérium du Dauphiné (June 3rd till the 10th) is THE pre-Tour race. This year should be interesting because it could be the first showdown between TdF favorites Bradley Wiggins and the almost-invisible-this-year Cadel Evans. Andy Schleck is also there and he’s really got something to prove in this race since he’s been sucking so badly all year.
I see Eurosport is covering the race this year, as is France 3 if you are living here. For other coverage check out Steephill TV.
