Graeme, I did the same on the City of Manchester advert a couple of months ago and for the same reason. One dead pair of lycra shorts and a saucer sized graze on my arse. I was luckily in the warm up and able to dash and borrow a hire bike and rent some shoes and not miss any track time. The hire bikes are decent and the confidence on knowing that you will not slip off adds to performance!
