"As well as the attraction of getting to run or ride through classic farmland, the Whanganui National Park, and view some of NZ's most iconic scenery, entrants really enjoy the sense of history that the Gutbuster invokes.
"This year we now have four events on offer with a new 18km fun run being added to the three usual cycling options including the 25km downhill only ride.
"Places are still available for all four events and although the 50km ride and the 18km ride or run can be entered on the day the 25km downhill only ride is limited to 20, so it's first in, first served."
Conway said the Gutbuster was aimed at the local Raetihi community who continue to be big supporters of the event.
"The focus of the day has always been on fun and participation. The Gutbuster has an event that suits all ages, abilities and levels of competitiveness," she said.
"In order to encourage people to give the event a go the entry fees have been kept as low as possible. Even with the $10 early bird discount on each event that expired last Friday the 18km ride or run is still only $20, the 50km ride $35 and the 25km downhill only ride only $47."
"As well as a great market day atmosphere there are some fantastic spot prizes on offer including season passes for Ruapehu Alpine Lifts and jet boat trips on the Whanganui River to the Bridge to Nowhere."
