Is it too late to back out....?

Well, I'm on the train to Edinburgh, trainers and decorated bra packed. I can't believe how quickly the Moonwalk has come around, and I don't think I've done nearly enough training. Still, I have some secret weapons, namely some walking socks that promise 'no blisters - guaranteed' (my solicitor is on stand-by if I need to sue later) and an ipod playlist with some inspirational songs including 'Eye of the Tiger' and the theme from Flashdance. If that doesn't get me round I don't know what will. Am now just praying that the rain will hold off....
