Cheers for all the support, I half expected to have the piss taken out of me and be told to just get on with it. Is ther any videos on sites like youtube that I may find of help.

Does anyone have any accurate info on these and the other tunnels on the Endurance course, i.e length, dimensions and how many of them there are? Also what happens if anyone gets stuck, has this actually happened before? I don't want to sound all PC but is it actually safe? I have my PRMC coming up ...
