I picked a walk from the Ordnance Survey app. I’ve done many sections of it on previous walks, though mainly in the reverse direction. Interestingly the route was originally done as a bike ride, so I was curious to see what it would be like when walked. There was one long and steep section which was hard enough walking let alone biking. More interesting was a long section (see picture 1) that was so narrow I couldn’t see how it was possible to ride along or even to push a bike along. The path was uneven and sloped, with a barbed wire fence on one side making it potentially dangerous for a walker let alone a biker.
