Back for its seventh year on Saturday, March 28, the event has become a firm favourite on the must-do list for the fit and not so fit alike.

Titan Macquarie Mud Run president Rod Fardell said while the elite athletes are timed, the majority of participants walk, run or dress up to take part.

"Around 95 per cent of participants dress up and they act as a team and help each other out," he said.

"All types of fitness levels, shapes and sizes take part."

For those new to the concept, a mud run is an obstacle course that takes participants through mud, of course, water and there's 28 obstacles you can choose to tackle.

"You'll be following the river right around, over fences and wool bales, you'll climb peg boards and go under cargo nets, go in the river and carry the odd object," Mr Fardell said.

"If you're thinking it'll be a world of hurt and you've got to be fit, that's not correct."

Dubbo Regional Council's soon-to-be-constructed ninja warrior course will also be ready in time for the event and it will be part of the course.

There are adult and child categories, with children as young as five welcome to enter.

"Parents are allowed to go alongside them, but not in the [children's] event," Mr Fardell said.

"We had 800 kids last year and we usually get 800 to 1000 adults and they travel to Dubbo from everywhere."

So far 400 child and another 400 adult entries have been received for this year's event.

The mud run is a not-for-profit with all funds raised going back into the Dubbo community.

Mr Fardell estimates the mud run has raised $400,000 since it began and that money, along with contributions from local and state governments, has created a range of permanent projects for the community.
