The current edition of this event is on 1 April 2018.
The Raetihi Gutbuster on Sunday, 5 April 2015 is a fun way to experience the scenery and history of the Raetihi-Pipiriki road that lies between the Tongariro and Whanganui National Parks.
There are 18km running and bike ride events, a 25km downhill ride and a 50km ride. All events start and finish at the Waimarino Museum, following out and back courses, except for the 25km downhill ride which gives you a bus ride back to the museum at the end, and means you get to miss out on the uphill part of the course.
Great Spot Prizes include Mt Ruapehu Season Passes, and jet boat trips to the Bridge to Nowhere. The start and finish area at the Museum has a market day atmosphere with cake stalls, BBQs and coffee vendors.
