On stage 9 in the Tour de France, Thomas Voeckler claimed the yellow jersey after being in the breakaway. For the following week, Rolland would help Voeckler defend the jersey over legendary mountain passes at Luz Ardiden, the Plateau de Beille and the Col du Galibier. Rolland gained acclaim for his strong work in defense of Voeckler's yellow jersey. Following the 14th stage of the Tour, Lance Armstrong referred to Rolland as a rockstar. Rolland won the 19th stage at the top of Alpe d'Huez, beating Olympic gold medalist Samuel Sánchez and two-time Tour champion Alberto Contador. The victory also won him the white jersey, which he successfully defended in the 20th stage, as he finished the Tour 10th overall.
