Even on the descent, the yellow jersey group had long since stopped any concerted chase effort, effectively conceding to Schleck.
Contador changed bikes near the bottom of the descent, perhaps simply changing to a special bike for the final climb. Still it cost him time and effort to get back to the group and then to face the challenge of chasing Schleck.
Schleck moved into the virtual lead as the gap to Iglinsky went under a minute between the final two climbs. He and Monfort had joined forces with Roche, Devenyns and Silin, and they caught Iglinsky with 30km to go. Behind them, Euskaltel finally moved in to lead the chase.
The yellow jersey group got larger as the stage went on. The gap had gotten smaller, but then moved back up to three and a half minutes, as Euskaltel moved out of the lead. The reason for that became clear later, when Samuel Sanchez became one of the first of the favourites to fall out of the group.
Monfort sacrificed himself for his captain, doing the majority of the lead work in the breakaway, before burning out and dropping back with about 17km to go. The group had become a trio of Schleck, Iglinsky and Roche at the 15km marker, with a lead of nearly four minutes.
That was enough for Contador, who finally moved to the head of his group, sharing the work with Evans. The Spaniard soon dropped back into the group though, leaving Evans at the front. Further up the mountain, Schleck was naturally at the head of his group as well, as the other two saw no reason to help him win the stage and possibly the Tour.
There was much discussion - not always a happy one - within the chase group, as no one appeared willing to take on the responsibility of chasing. Meanwhile, the gap extended beyond four minutes.
Evans tried an attack, but the others climbed on to his wheel. He continued to grind away at the head of the chase.
Schleck led Iglinsky up the final climb, as he turned to go up the final 8km with a 3:50 lead. And on one of the first curves, Schleck turned on the power and took off alone on the fan-filled road.
The chase finally started bearing fruit, as the gap came down under Evans' hard work. The group got smaller and smaller, with even Contador eventually having trouble hanging on. He finally gave up the fight and fell back, burying his chances of repeating his victory in this year's Tour.
