The field split even more on the way up the Col de la Bonette, to the point where it was difficult to call any particular group the peloton. Christian Vande Velde was the first GC contender to be dropped from the yellow jersey group, cracked by the pacemaking being done by Andy Schleck. A chase group paced by Cyril Dessel and Yaroslav Popovych caught Schumacher some 3 kilometers before the summit of the Bonette. John-Lee Augustyn, attacked from this group shortly before the summit and was the first to reach the top. He later skidded off the road and tumbled down a steep decline on the dirt beside it, losing his bike. He had no choice but to wait for a service car with a spare machine, and thus lost the chance to rejoin the leading group.
