Costa repeated his feat of three stages previous by taking victory in stage nineteen, by attacking on the final climb of Col de la Croix Fry and soloing to the finish in Le Grand-Bornand. There were no major changes at the head of general classification. Stage twenty, the penultimate stage, saw the leaders of the general classification still together at the head of the race with remaining of the final climb of Mont Semnoz. Quintana and Rodríguez then attacked, with Froome the only rider able to bridge, and again the pair pulling away, with Quintana managing to hold off Rodríguez by eighteen seconds to take the stage win, with Froome a further eleven down. Contador came in seventh, two minutes and twenty-eight in arrears, dropping to fourth overall, with Rodríguez moving up to third. With the double points gained with his win Quintana secured the mountains classification.
