If you are after an event with bucket loads of laughter, fun and mud, then the McDonald's Mud Muster on Saturday, 17 October 2015 is for you!
This year it will take place at the Shelter View Jetsprint Track, 12km north of Wanganui.
There are 3km, 5km and 10km events, along with a 5km teams race. In the teams race, all teams must be made up of four people and can only have a maximum of two males per team. You must all start at the same time and cross the finish line together - and it's as easy as that!
