I understood Pena Cabarga, he was fine, the only to follow Horner's attack but the he went into the red trying to match the insane watts produced by the American. He had no choice, the climb was short and he could not have maintained his usual pace without loosing more. He managed to limit the loses and his performance was normal for him coming within few seconds of Purito and Valverde. But then yesterday he lost it in the final hundred meters of a Cat2 climb. This I can't quite understand. Was he indeed feeling weak? Was this an intentional move to loose the jersey and get a few hours more of rest (he was complaining about the interviews and all the stuff that the leader has to go through after the race)? Is he betting on Angliru? All the major contenders had the bad day except Horner. Maybe today? Rain? I still have confidence in Nibali. We'll see.
