Well, rode it last night. Parked in Langsett Barn, up to North America, through the gate, up Cut Gate, down to Slippery Stones Foot Bridge, did a U turn and went back, but descended down to North America from the sign post, left again through the gate, and did the zig zags to Crooklands Wood.
I have to say I was underwhelmed. Perhaps its all the stuff I had read about it "legendary MTB trail" that got my hopes up too much, but I found it pretty ordinary to be honest. The "out there" feel was pretty good as its quite remote, so a solo ride was quite relaxing.
Anyway, I've ticked it off my "to do" list, but I wouldn't be rushing back to be honest, not unless I do it as part of a Doctors Gate, Cut Gate , Longdendale ride.
