Here are five things I've discovered about the Coast to Coast Walk...
1. During its 200-odd miles, the walk ascends and descends the equivalent height of Mount Everest.
2. Though the walk passes through three National Parks, crosses the Pennine Way and at times joins both the Cleveland Way and the Lyke Wake Walk, it is not itself an 'official' national trail.
3. An athlete one completed the walk in 37 hours.
4. Wainwright, who devised the walk, never carried a compass.
5. The route crosses Britain at neither its narrowest or widest point; it was chosen for the quality of its terrain and scenery.
