In reply to balmybaldwin:
Chap we were talking to said there's loads of gravel on the descents - we assumed because there'll be lots of inexperienced cyclists (and crap descenders like me) they would be dodgy. There still seemed to be plenty of people managing to fall off anyway.
Like you say, they always have the option to cut it short - as it was we were finished at about 10:30. At which point the bloody household cavalry trotted up the road that everyone was collecting their bags etc on so hundreds of freezing cyclists had to haul their bikes and stuff over the barriers. You'd have thought for one day they could go a different way
