The first week is always very unpredictable, as the GC guys normally just ride through it and form is not at its peak. For those reasons many riders have been caught out by the pace and hard parcours. The Pyrenees would be a better test for many riders and stage 10 became a nuclear test!
Nothing happened much until the final climb of the day, a 20km climb with over 1,200 metres of altitude gain. By the time Froome attacked with his trademark Speedy Gonzales impression on the pedals, Nibali and Contador had started to lose ground in a very unlikely fashion. Froome would go on to win by a big margin over teammate Porte and rival Quintana. Geraint Thomas proved once more to be an invaluable domestique and showed much improved climbing prowess.
