Purists will doubtless load their worldly possessions into some enormous rucksack, arching their backs against the weight as though they were at SAS training camp!
Others might decide to travel light and wear the same underwear for four days!
There may be a happy medium rucksack-wise but more mature, less rugged walkers might consider using a local taxi to transfer their luggage and just carry a lightweight day-sack with them.
One local firm that offers luggage transfers between Hotels, Pubs, hostels or B&B's is Peak Premier Travel. They also provide a "one way walk" service where customers can be dropped off at one end and collected at the other or use their own car at the start or finish.
