Trials are based on the ability of competitors to drive their vehicles over difficult terrain, including hill climbs, mud bogs, and going up steep hills, over rocks and along banks. The course is made up of a minimum of 28 short obstacles. Blue pegs mark the start and end points of the obstacle, and the boundaries of the obstacle are indicated by red pegs (on the right) and yellow pegs (on the left).
The driver and co-driver attempt to negotiate their vehicle through each obstacle as far as they can, and vehicles from all classes drive over the same obstacles.
Classes include production, production-modified, super-production, modified and super-modified.
Each event has an overall winner and class winner for the day. Points won go towards deciding the overall and class winners for the different zones and national placings at the end of the season.
There will be food trucks and coffee cart at the Te Puke event, at which money will be raised for Waipuna Hospice.
Entry is $25 for a family (2 adults and 3 children) or $10 per adult and $5 per child.
