“I say, old chap. Why don’t we don our best tweed attire, and go for a little jaunt through the big smoke on our bicycles?”
“Hear, hear! That’s a splendid idea, old chap.”
I’ve no idea if that was the actual conversation that led to the first London Tweed Run, in 2009. It must have been something along those lines because, as far as I can tell, there’s no purpose behind the Tweed Run other than going for a ride and looking rather fabulous while doing so.
