Tally ho, chaps!

Today was the 2012 Tweed Run - "a metropolitan cycle ride with a bit of style" as described by its website.

Several hundred riders donned their best tweed, polished their bikes and headed into central London for a leisurely cycle through the city.

These two are brother and sister and seemed the perfect embodiment of the day. But I can't help seeing just a passing resemblance to Miss Penelope Pitstop here. That's the girl, by the way.
