After briefly visiting the 'taking her up Moonlight....' thread (and it's predictable tangents), I just thought I'd say that the one thing that has struck me about these recent 'challenges' folks have been doing is that they are indeed that, challenges.
I can't stand being asked to sponsor folks for doing nothing more than break sweat - At least what Davina McCall and John Bishop have recently done, and Alex thingy is about to do, are hard (for them) or scary.
Good on 'em.
