The Course:

The idea for The Mudder came from farm owner and course designer Andrew Stewart. In 2013 Andrew came up with the concept of a unique mud run to take advantage of the unique terrain of his family’s Rangitikei Farm. This landscape is naturally hilly and by creating a course that also took in some of the unique geographical features, such as swamps, dams and springs, he was able to deliver something truly unique to mud runners in New Zealand. The course winds its way through a working sheep and beef farm so entrants are sharing the course with sheep, cattle, horse and some coloured pet sheep. Being in such close proximity to farm animals just adds to the unique flavour of this event.

While there are some man-made obstacles to test entrants, the obstacles that truly challenge are the natural ones. Here are some of the favourites from the previous three years:

Slog through a bog: Leaving the flatter part of the course behind, the first creek crossing turns into a hands and knees slog up through a spring fed bog. This little gem turns from grassy gold to gut busting gloop after the first few punters have been through, but always gets laughter and smiles and of course everyone gets filthy.

Rubber Island: Leaping across (or through) a water hazard, entrants find themselves on a spongy, floating island that moves with each step. This is a unique geographical feature that creates a sense of bouncing on water. Getting off the island is not easy and requires a slippery struggle through waist high mud.

Monster Mac: This old tree could be straight out of a Hobbit movie and has a trunk and branches that have to be seen to be believed.

Slip and slide: Leaving the hills behind is a great feeling so why not celebrate with a super, slippery slide. Or two. Or three….

The short course is about 3km long, the full course about 5km and those that wish to really challenge themselves can do the two lap course which is about 8km.

Please take time to bring some cash with you. There are no EFTPOS or credit card facilities on site. There are a number of ATM’s in Marton and also numerous shops so take time and arrive prepared.

At this time of year, the weather is a very fickle beast. Please dress accordingly for what can be winter like conditions. Entrants should wear warm undergarments (preferably woollen) on the skin to keep warm during the event. It is strongly recommended to bring a second clean pair to change into after the event. Bring some warm clothes, jackets and beanies to wear afterwards and please take action if you are feeling the cold. The mud will be cold and the water will be colder so take some time to think about the clothes worn on the day.

The address of The Mudder Event HQ is 498 Makuhou Road which is searchable in many GPS systems. We are operating a traffic management system on the day and we ask that:


There will be signs and marshals to direct you. Please be patient and careful if you have to wait for a red light and remember to get everything you might need from your vehicle before walking to Event HQ. You will need to allow time for delays and walking from your vehicle. DON’T LEAVE IT TILL THE LAST HALF HOUR OR YOU MAY MISS YOUR START! If you are leaving early after the event please follow instructions and leave Makuhou Road as shown.

This will be located in one area for convenience and include a BBQ sizzle, hot food and chips and coffee cart. Please support these businesses and re stock those depleted calories.

All registrations will be handled inside the woolshed. You will receive a number and timing chip which will need to be securely attached to your shoe. You should bring some tape for your shoes as some of the mud is very hard to get your feet out of sometimes (This is a very good idea!). There will also be a secure bag drop area inside the covered yards where you will be able to leave your bags. We ask that you limit loose items as you will only be able to check in one item per entrant.

There will be 12 individual changing rooms in the woolshed and also a communal female and communal male change room. Please respect each others privacy.

The briefing will take place in the covered yards and will start at 10am. This will be followed by some warm up music to get those limbs loose for the event.

Entrants will start in 8km, 5km and 3km waves. Please be sure to follow the instructions of the Race Officials in the starting areas, and don’t forget to warm-up beforehand! It is also VERY IMPORTANT to follow signs on the course so you complete the correct distance.

Once you have finished please follow the directions into the finishing pen. Here you will be able to sit down and relax. We will also need to you to remove your timing chip and place it in one of the provided buckets before leaving this area. We ask that everyone complete this process so all timing chips are accounted for. We do have 12 hot showers for you to wash up in after you have completed this process.

This will only start once all entrants are off the course and will take place in the covered yards. There will be certificates for place getters in all categories as well as for the Teams Challenge. The will also be a shield for the Best Dressed on the day and a fantastic assortment of spot prizes to be drawn. Remember you will have to be at the prize giving to be eligible for a spot prize so please hang on to your race bib to avoid disappointment.

The Mudder is definitely a spectator friendly event, and we encourage friends and family to come along and join in the fun. We ask that all spectators please stay off the actual course and follow instructions. Rangitikei Farmstay is still a functioning farm, so the last thing we want is gates left open or fences broken – please respect this rule.
