No one believes you Adam, it's obvious you have never done it. There is a big difference between a man made road / cycleway and a rough public right of way.
I could not walk some of the public footpaths near me at night without torches.
I have never been to area. Never said I had.
Google Maps and Hardy Boy say Pages Lane merges into a wide footpath. It is the prosecution route.
Wilkinson, RB and Gunfure Graffiti say The Sea Wall terrain is good.
You said paths between fields are wide as tractors go down them.
