For some of them, the three-day walk from Turakina Beach to Palmerston North will be the fourth section of trail they have done.
Mrs Harris is organising support vehicles for those who get tired on the eight-hour February 13 walk, and says Bulls firefighters will be the group's medics.
Having the trail pass through Bulls would be great for the town, she said, and a family in Brandon Hall Rd was setting up a homestay to host walkers.
Those walking on February 13 are to head south on the beach, then head inland through Santoft Forest to reach Bulls.
They are advised to bring plenty of food and water, and wear comfortable footwear.
Anyone who wants to come can find out more from Mrs Harris by ringing (06) 322 0051 during work days or 021 174 5951.
