Tour de France favourites clash at Tour de Romandie

The 2012 Tour de Romandie gets underway in Switzerland on Tuesday with a 3.34km individual time trial serving as the prologue. Four tough stages then follow before the race wraps up in the Alpine town of Crans-Montana on Sunday afternoon. And with the two favourites for this season's Tour de France lining up it promises to be a fascinating few days of racing that could have implications for the biggest prize of all this July.
