Did this at about 8 pm and its pretty good as well as scary in the blind bends. The best bit being the vertical cutting between Shere and Ewhurst. The initial bit after coming off the A246 and the final bit in Gomshall are somewhat okay (unless your a fan of grazing sheep or an usual Surrey Village)
The rest is quite challenging and technical and add the idiots in their cars who cant be bothered to dip their main beams....making it a good evening ride if you want to escape the usual crap on TV on a Sunday evening!
