In the twentieth stage, the riders went through the Alps, to finish on the Alpe d'Huez. Roche finished in fifteenth place, and lost the lead to Delgado. The pivotal stage was stage 21. In the first part of this stage, the Colombian cyclists of the Cafe de Colombia team (including Luis Herrera and Fabio Parra, fifth and sixth in the general classification) kept a high pace, and many cyclists were dropped. Roche, Delgado and Mottet decided to work together to get rid of the Colombian cyclists on the descent of the Galibier, out of fear that Herrera and Parra would leave them behind in the next climbs. Their plan worked, but Delgado's teammates were also dropped. Roche saw this opportunity and escaped, climbing the Madeleine in a small breakaway group.
