the organisers are a bit unique but don't let that put you off. They are great people and will make sure that you get round (or off the course) safely. I did this last year and it's one of the most memorable and fantastic races I've ever done. Come and join in the fun.
But... you are expected to be able to get round on your own, ie be able to navigate in the dark, whatever the weather. There are miles between the marshals and might not be any in the places where you're most likely to make mistakes. So it's not like you'll be able to see the next one. But they do flag those sections, but again, if the mist is down you need to have an idea of where you're going if you're not going to slow down to a crawl.
I ran the course in daylight before I did the race. Don't know if that was cheating, but it really helped.
Foodwise I just had an enormous burger king meal on the way there, then water and fruit cake. Just find something that works for you.
They'll sign you up on the night - at least they were last year. But they really don't have any safety pins.
