I rode at Thetford at the weekend. We did the Red and the Black.
The red was in a worser state than the Black. Both are muddy, but the Red was really bad. The Black is occasionally more covered than the Red, so that may have something to do with it.
Since I last rode it in January the Beast section on the Black was a lot tamer; maybe some erosion.
Still a great day out though. Hard work, the mud and the sand make it quite a workout..
It's a great place; I just wish they could open up more of it with waymarked routes. Most of the regulars seems to avoid the mareker routes and hack off on their own secret routes..
