In London on September 2005, a few weeks after the 7 July 2005 bombings, Metropolitan Police required the organisers to provide a route six days before the event and placed strict restrictions on riders, under threat of arrest. The threat was retracted when politicians and cyclist groups objected. In October 2005, the ride had close to 1,200 participants, significantly more than usual. A long stop in Parliament Square, part of the government's exclusion area in the Serious Organised Crime and Police Act 2005, led to a slow and cumbersome ride.
