"There are health benefits to walking. It's easy to do with family and friends, it's quite a social event. There's always a sense of achievement especially if you do two days."
Shaw said the event drew international walkers as the festival belonged to the International Marching League and International Federation of Popular Sports walking organisations.
Walkers can collect a stamp on their IML passports by participating.
Rotorua musicians will also perform at the start and finish lines during the festival, which is on the same weekend Crankworx starts.
Shaw said the committee was working closely with Crankworx organisers around running the events in the forest at the same time, but it would be exciting for walkers to see the mountain bikers.
He encouraged people to register for the festival even if they'd taken part before as the organisers tried to change the routes annually.
"For locals, 25 years, it's a pretty well-established event and a lot of people have not done it. They'll meet and walk with people from around the world and international walkers are keen to meet locals," Shaw said.
"They'll probably walk in places they've not walked before. I can pretty well guarantee that."
He said while it was possible to do the walks at any point, the festival also offered entertainment, a social aspect, and a chance to walk with people from around the world.
Early bird entry is open until Monday .
