The Tweed Run will be returning to London on 10 April. Lots of riders dress up in 1920s gear - caps, plus-fours, serge jackets, that sort of thing - and troll around the capital making people smile. (Why do buses cut you up and shout abuse if you're wearing reflective gear and signalling properly, but hang back and grin and give you time if you're dawdling in Harris Tweed and smoking a pipe? I don't get it.)
They've done various rides out from London in the past, and have been featured in various magazines, but the first London run was last year (right). Registration starts on 27 February at the Tweed Run website.
