Rezillo and I did a miserable 60 miler today round some of the route of the Sunrise, miserable because the weather was utterly foul, wet and cold. However, the main point in posting is to warn any potential riders that the roads are in an awful state following last weeks rain. There's sand, grit, pebbles and small flints all over the place but especially in dips in the road. If you don't have Kevlar belted tyres on the bike, get some or be prepared to change tubes. If you haven't ridden these roads before be aware that east of the A12 the land is very sandy and I would not advise charging down hills into a corner. Chances are the surface in the corner will be very loose and you risk becoming a serious cropper. Any part of the route from about Melton to Blythburgh is potentially a problem but I suspect other areas could be almost as bad.
