On Friday, while on our way to see DJ Shadow over in West London (see above), we found ourselves seated opposite one of the Tube Challengers who were racing around Zone 1 (we could tell because he was wearing a sticker that said 'Tube Challenge.com' on it).
The guy looked pretty frantic, scouring his Tube map, trying to calculate the shortest route, before jumping off at High Street Kensington and running off into the crowds.
We didn't talk to him because he looked a little distracted, but we did take this surreptitious snap. So, was it you? How did you get on?
We've also spotted our tube challenger on the far right of Annie Mole's picture taken at the post-challenge piss up, which (somewhat ironically) accompanies her report on the new I'm up for a chat on the Tube campaign.
