Dubkev I think the main issues are (in general, not with you) fatigue and competency. The ride has 4k feet of climbing - 1k more than Brighton, but that isn't such a big deal - but riding through the night increases the fatigue so it can make the ass-end a little hard going when it's mile 70 for you and 3:00 am. And once the trains stop around 11pm there's no way to bail from the ride really, so having enough energy, good lights (check), can fix a puncture in the dark (check), and generally not riding like a dick (check) means that the group will stay mostly moving and everyone's safe. The main idea is that it's fun for you and the whole group, eveyone riding a nice pace consistently. I know you can do it and would be fine for it, but if the thought of riding to Brighton with a little bit of a hangover makes you feel slightly hesitant I'd give it a second thought. Make sense dude?
