The Tweed Run is a group bicycle ride through the centre of London, in which the cyclists are expected to dress in traditional British cycling attire, particularly tweed plus four suits. Any bicycle is acceptable on the Tweed Run, but classic vintage bicycles are encouraged. Some effort to recreate the spirit of a bygone era is always appreciated. The ride dubs itself "A Metropolitan Cycle Ride With a Bit of Style."
Among the inspirations for the Tweed Run was Jack Thurston's now disbanded Tweed Cycling Club, and several vintage attire-themed rides which were held in the north of England in the 1990s.
Although previous cycling clubs have hosted vintage-themed rides before, the very first Tweed Run was held on 24 January 2009, and organised via London Fixed Gear and Single Speed, an online cycling forum. The second run was held on 10 April 2010, for 500 registered riders.
Since then the Tweed Run has become an annual event with major sponsors. Participants are limited to 500 (due to health and safety rules) and due to high and popular demand a ticket ballot system has been in place.
