The Pennine Way is a National Trail in England. The trail runs 429 km (267 mi) from Edale, in the northern Derbyshire Peak District, north through the Yorkshire Dales and the Northumberland National Park, it ends at Kirk Yetholm, just inside the Scottish border. The path runs along the Pennine hills, sometimes described as the "backbone of England". Although not the United Kingdom's longest trail, it is according to the Ramblers' Association "one of Britain's best known and toughest". (source)  Thank you Andy!
