These may be cross-country paths, or may follow roads or other ways, and often intersect with many other trails. Examples are Wainwright's Coast-to-Coast path in northern England, and the GR 10 in France. The English Coast to Coast route, despite being amongst the best-known long-distance walking routes in England, is not an official National Trail, but simply a series of connected pre-existing rights of way, roads and open country with some informal links between them. There is also a coast-to-coast mountain-bike route in northern England that has the same trailheads as the walkers' path. GR 10 is a French GR footpath that runs the length of the Pyrenees Mountains, roughly paralleling the French–Spanish border on the French side. It runs west to east, from Hendaye on the Bay of Biscay to Banyuls-sur-Mer on the Mediterranean Sea.
