You should have no probs up the climb from your comment below Chris. There is a steep climb before the main climb starts so don't hammer up it or you won't have recovered in time. For people who've never done a long climb before my suggestion would be to take it easy from the start and you'll find in the last few kms you'll probably want to change up a gear or two once you've got into a rhythm because it'll start to seem quite easy. I would not rely on the food stops available and bring my own. When I rode it last year a lot of the refreshments were gone by the time I got there and I was about middle of the pack so to speak. But I am also picky with food/drink on rides :D The last 10k or so downhill are a blast but watch out for the biggest obstacle, other riders who can't descend!
