Gary Imlach and Chris Boardman present highlights of stage 10. This classic stage for the long-distance escape artists starts with 24km of relentless climbing on the category one Port d'Envalira. 170km of sinuous roads follow, before the crux of the stage - the category three ramp of the Cote de Saint Ferreol. Just 7km before the finish line, it has the potential to fragment the front end of the race, so sprinters beware. Commentary by Ned Boulting and David Millar with Daniel Friebe reporting from the roadside.
