"Sometimes it's quite tricky holding on to it, especially going down the mudslide."
There are always new obstacles but Mrs Clare would not say what's new this year.
"I can't give away too much."
The festival runs from 11am to 11pm in the Rangitikei town - "rain, hail or shine". As well as the obstacle races, there will be dog trials during the afternoon, showing what huntaways can do. Then at 5pm, four teams of contractors compete in a speed shearing challenge with a twist, organised by Shane Ratima.
There will be 20 stalls, selling "quality handcrafted goods" like olives, cheeses and wooden toys, and a bouncy castle and demonstrations to amuse children. The day ends with Palmerston North band Six Chairs Missing playing from 7-11pm in a marquee, for a price of $10. The festival costs about $60,000 to run, Mrs Clare said, and it has many sponsors.
"It's an event for the community and it's promoting Hunterville as well."
