Thanks Damon,
received the MR24 handbook yesterday through the post. I'll need to look at it more thoroughly, but it seems none of that is mentioned!
in the riders instructions it says that night cloths and lights can be handed in to the signing on steward to be taken o prees island for the rider.
If you want kit, food, drinks etc taking down there, my wife will ferry things down there for you. She will be asleep during the night but can leave your kit next to my milk crate of bottles t preese. Look out for the dark grey high top camper van in the car park at farndon before the start and ask for richard if you want.
