January 24th, 2009, London hosted the first ever Tweed Run. The event was organized by London Fixed Gear and Single Speed.  Riders wore traditional British cycling attire, namely tweed.

Tweed is a coarse unfinished woolen fabric closely woven in either plain or twill weave.  Tweed was often worn as informal outerwear because it is durable and moisture resistant… perfect for cycling?
