Chris Froome showed the first signs of cracking on the second climb of Alp d.Huez and called for his team mate to help him. He needed and energy gel which Richie Porte got from the team car. The thing is that the rules state that riders are not allowed to get food or drink from the team car during the final climb and so Froome has been penalised by 20 seconds for his action.
Was it worth it? As it happens, Froome gained a further 57 seconds on second placed Alberto Contador so even with the penalty, he still gained a further 37 seconds taking his lead to five minutes and eleven seconds.
