I've heard about the track in lordswood, apparently there's a good 90 minute xc loop too, all i've found there is a single track that has a road gap jump in it, quite good fun. Be interested in more.
thomthumb – didn't know about rogate, is it common knowledge or a secret track (i'd be interested in finding out more)
The winchester track was hard to find the start of, but easy once you knew, the way in was located at the final bend on morestead road before the hill down to the motorway junction (if my memory serves me) I can't find anything on google earth to suggest the field part of it still exists. Encouraging to hear 18 months ago something was going on near there, it's a super nice short steep bit, be a waste to just leave it be.
