Better signed, better ride, loads less riders than HONC. Try this enduro out next year. http://www.bucksoffroadclassic.co.uk/
Alex and I had a WONDERFUL day yesterday. We did the 70K. He on his beloved 29er rigid ss, I on my cyclocross bike. Recommend doing this (as well as HONC) on a cross bike or at least a rigid mtb. The ride is mostly bridleways and some paved road. No need to lug all the weight of sus. The lighter the better. Very pleasant people running the event. Hope to see you next year!
