2011 Tour of Britain

The 2011 Tour of Britain was the eighth running of the latest incarnation of the Tour of Britain and the 72nd British tour in total. The race started on 11 September in Peebles, Scotland and finished on 18 September in London, England, with the race also visiting Wales for one stage.

The race consisted of eight stages – down from the original itinerary of nine stages due to bad weather – and included the Tour's first individual time trial since 2007, as part of two stages on the race's final day, with a criterium to finish the race. The race was held as part of the 2010–2011 UCI Europe Tour, and was categorised by the UCI as a 2.1 category race.

The race was won by Rabobank rider Lars Boom, who claimed the leader's gold jersey after two stage victories, as well as a strong finish on the individual time trial stage. Boom maintained his advantage to the end of the race, with a winning margin over runner-up Team Sky's Steve Cummings of 36 seconds, and Team NetApp's Jan Bárta completed the podium, 19 seconds behind Cummings and 55 seconds down on Boom.

In the race's other classifications, Team Sky's Geraint Thomas won the points classification, An Post–Sean Kelly rider Pieter Ghyllebert led the sprints classification from start to finish and Jonathan Tiernan-Locke took home the polka-dot jersey for Rapha Condor–Sharp, as he finished at the top of the mountains classification. As well as Thomas' points victory, Team Sky finished on top of the teams classification.
