Families are invited to get down and dirty at Matahui School's first-ever mud run this Saturday.

The independent private school in Aongatete is hosting an inaugural mud run on November 7, giving participants the chance to run, jump or crawl their way through a 2km muddy course.

Event organiser Matt Griffiths says the land owners of the muddy wetland beside the school agreed to let organisers use the area for the inaugural event, which aims to raise the school's profile.

'Some of the funds we will raise, certainly in the future, will go towards the planting of that area and the development of a conservation area there.

'But at this stage we'll be making a donation to the Katikati Fire Brigade.”

Matt says participants will navigate an obstacle course through mud and farmland, with a giant mud slide at the finish line.

'The entire course isn't muddy, but there is an area where people will become very, very grubby.”

'The obstacles aren't so challenging that people can't complete them. It's not like a military-style mud run. It's really open to all ages and abilities. We just want people to come out, have a good time, and have a laugh at themselves.

'Some people will run as fast as they can and want to be first across the line, that's just human nature. But it's not a race.”

Matt says a focus of the Matahui Mud Run is to raise the profile of the school, with a small donation made to Katikati Volunteer Fire Brigade on the day.

'They're bringing a water tanker to help hose people down at the end and will be located pretty much directly above the top of the slide.

'We're really conscious of not wasting water. So, as they wash people down that water will flow down the slide and help to irrigate that.”

There'll be a range of events on the day for different age groups, with spot prizes and special prizes for the wackiest costumes.

The school will also host 80 vintage motorcycles for about one hour about lunchtime.

Matahui School's inaugural Mud Run is on Saturday, November 7, from 11am-2pm. Entry costs $5 for children and $10 for adults. People can register on the day. Hot food and cold drinks will be available.
