Happy to use your route User10571.............
Bear in mind my comment re: the pretty and the traffic-lite not really starting until you get to Broxbourne.
The pretty you can't really do much about, but traffic-lite can be achieved by deploying an early start - although I appreciate that could compromise those who are arriving at the start by train....
In the event that I'm unable to make the ride, be sure savour the long winding descent, with good surfaces and excellent sight lines, and a white pickety fence as it crosses a tributary of the River Stort, and you cross the border from Herts into Essex.
I'm not going to tell you where it is as
a)There's a big sign saying 'Welcome to Essex' and
b) You'll know you are there because you'll be grinning not only from ear to ear, but all the way round the back of your head
