I’ve put the course into RideWithGPS. Link here for you all:
Its come out slightly short. There are some confusing junctions and loops so I think I have missed a turn somewhere. Interestingly they are saying 940m elevation, but this as got nearly 1400m
Certainly does look like a fast course. BBS giving me a 5:30 split on 200w, compared to Lanza which is nearly 7 hours.
Roads are going to be terrible state. You can tell when you are in East Sussex as you head down the A27 as your car stars shaking. A lot of the route uses the A22 which is the main North/South trunk road through the county. But is narrow single carriageway in most places. Can see some irate drives getting the hump. Rest of it is narrow B roads
