Just thought i might add what i thought. I go to delamere but like to do the trail centres aswell.
I love riding the singletrack and do try to put loops together etc, i know of a reasonable amount of the tracks but would love to know of more of them so am getting some lights together and will join in the monday evening mayhem.
In my opinion, the two things that would be of benefit would be a guide or a marked out loop (maybe markings that only the mtbers know about etc) and a bit of help on the really soggy bits, there is one bit around a fence that i know of that is particularly bad that needs some sort of help, it was soggy in the summer so god knows what it is like now as i try to avoid it.
These two items would be of help i think without going to the extremes of hard surfacing routes etc.
I would be more than willing to help with anything, i am only down the road and know delamere pretty well from growing up in a nearby village.
