Tour de France: Stage 12 preview

The riders of the Tour de France will face their toughest challenge yet in the high mountains of the Pyrenees on stage 12. Departing from Lannemezan, the 195 km stage will be one to fear for the sprinters, and one to attack for the climbers. The GC contenders looking to dethrone Chris Froome (Team Sky) will need to strike today, to see if the last two days have left him and his team vulnerable.
