Course: Any Pyrenean stage that goes over the mighty mountain passes of Tourmalet, Aspin, Peyresourde and Portillon merits the greatest attention from the race favorites — even though this one then continues into Spain for another 40km to finish on the long, but gently graded climb to the Pla-de-Beret summit. If this Tour is going to be a free-for-all, then climbers who want to shoot for the polkadot jersey or a high GC placing must attack on this challenging day. So look for likely KOM candidates to infiltrate the breaks that are bound to form on the narrow, winding roads that precede the Tourmalet. If GC contenders wait until the final climb (13.5km at 5.4 percent) before making a move, they will end up gaining (or losing) very little time.

History: This is the first time that a Tour stage will finish at Pla-de-Beret, but stage 8 of the 2003 Vuelta a España completed a similar course (except for the Tourmalet). At the Tour, the Tourmalet stage in this more difficult west-to-east direction (18.4km at 7.7 percent) has almost always caused major upsets.

Stage 11: Tarbes to Val d’Aran/Pla-de-Beret - 206.5km

Favorites: A stage finishing in Spain has to motivate the Spanish riders. Should a breakaway succeed, look for the Euskaltel team’s Iban Mayo, Gerolsteiner's Georg Totschnig or Rabobank’s Rasmussen, whereas a larger group arriving at the foot of the Pla-de-Beret will favor Valverde.
