300 miles of secret cycle paths have been discovered

A cycling enthusiast has uncovered nearly 300 miles of hidden cycle
paths that were built in the 1930s. Carlton Reed discovered these
forgotten cycle paths whilst he was working on a book. He’s set up an
appeal to try and bring them back into use. A lot of the paths are
overgrown or buried now, but some could still work perfectly as cycle
ways if local councils realised what they were.
