The course is on the sheep and beef farm run by Stewart and husband Andrew. It starts at their Rangitikei Farm Stay Woolshed 12km north of Marton and there are 3km, 5km and 8km options.
Although many of the obstacles are kept secret until the day, participants can expect the course to be built around natural resources on the farm including a floating island to crawl over, bogs to wade through and hills to climb.
"Everyone's favourites like the waterslide are still around but there are definitely some new obstacles that have been added."
