I found it at last. A 100-mile walk that requires no back-up or bag-carrying service, where you can camp, b+b, bunkhouse, or hotel and, if you like, spend every night in the same location as the first. The reason? The Settle to Carlisle Way follows, and passes through, or very near, every station on the most scenic line in England, between Settle and Carlisle. Simply finish a days walking and catch the train back to where you started. Return tomorrow and start again.
