The early breakaway consisted of 5 riders and was given a lead of up to 23 minutes by the peloton. In the break were
Oleksandr Kvachuk,
Mohammed Said Elammoury,
Jackson Rodríguez,
Diego Tamayo and
Matt Brammeier. In between the break and the peloton rode
Esad Hasanovic, who was chasing the lead group for several kilometres. He rode around 5 to 6 minutes behind them for some time. The breakaway almost lapped the peloton on the closing circuits, but the American and Belgian teams would increase the pace of the peloton and the gap began to fall. Elammoury was dropped by the other four with about 10 laps to go. Kvachuk dropped Brammeier, Tamayo, and Rodriguez but by the end of the seventh lap the gap had fallen to about 5 minutes. Somewhat like
the previous year's race, a large escape group went away, this time with 5 laps to go. The group contained 31 riders, including the previous year's champion
Cadel Evans, his teammates
Stuart O'Grady and
Simon Gerrans,
Edvald Boasson Hagen of Norway, Belgian
Philippe Gilbert, Dane
Matti Breschel and 5 Italians including
Vincenzo Nibali and
Filippo Pozzato. The group survived until lap nine although the peloton, led on by Spain, never let them get much of a gap. On the ninth lap Nibali attacked which decimated the breakaway and the peloton behind. Evans, Gilbert, and Pozzato were chasing behind at the end of the 9th lap, with the peloton 49 seconds behind Nibali. However, the peloton kept the pressure high and had pulled back all the attackers, including the early breakaway at the beginning of the last lap. On the final ascent of the Montpelier climb, Gilbert made an attack and Evans immediately tried to jump into his slipstream. However, Gilbert got away from Evans, who was absorbed by a chase group containing
Paul Martens of Germany,
Alexander Kolobnev of Russia,
Koos Moerenhout of The Netherlands, and
Fränk Schleck of Luxembourg. The group was not well organized and was brought back by the remnants of the peloton and Gilbert was also caught with 2 kilometers to go. Russian
Vladimir Gusev and Slovenian
Janez Brajkovič attacked just before the 1 kilometer to go banner and were joined by Dutchman
Niki Terpstra. Terpstra attacked with about 800 meters to go as the Danes tried to set up a sprint for Breschel. However, as soon as Terpstra was caught Belgian
Greg Van Avermaet launched the sprint. Breschel passed Van Avermaet on the left-hand side but
Thor Hushovd of Norway passed Breschel and held on to the finish line for the victory. Breschel would settle for 2nd while
Allan Davis of Australia passed Van Avermaet for the bronze medal. ==National qualification==
