I have just route checked the 100k version.
Arrivee is within 100m of Witham Station but in less than a km you are on a country lane on NCN16. From there the route passes through much of the best that mid-Essex has to offer and would show a different side to Essex for many that don't know it that well. It will probably be a bit more undulating than some would expect, (although admittedly that is a relative concept in the flatlands).
The first leg is straight into the prevailing wind which means that you have a tailwind for most of the second half when you need it.
All in all, it is a great route for someone looking at a first 100k or, like me, someone who struggles to fit in a 200 with everything else that happens in the summer.
As an added bonus, Huggy had arranged some very special mechanical cover. When I pulled over for a hedge stop and took the opportunity for a quick faff, none other than Alex Dowsett pulled over to make sure I didn't need anything.
Good luck to the braver souls riding the Sunday route check of the 200
