[visited 14/07/03] Well, I’m by far a cursus expert but I always thought they were much wider and generally bigger than this. However look at the pictures; it is a very strange track, it heads straight to one end of the barrow and it does go straight up a very steep hill. I would guess the central mound (and it is raised) is about 5 metres across.
Unfortunately I didn’t get to the end at the bottom of the hill due to time constraints, so I have no idea how far it went etc...
