Good route but jolly waggoners has closed down try bull much hadham or green man in widford for stop. If you fancy taking your bike for a dip there is a long ford if you turn down by the crown inn m hadham. Beware it is hairy as can very deep and full of gravel even though it is a road towards perry green!
It is a nice route but the bends don't really constitute a five in my opinon, well worth a look though
Some nice twisties is this relatively short section. Watch out for the 1 in 8 hill on the bend. Recommended stop here is the Jolly Waggoners on the way in to Much Hadham
