How do I transfer my place to someone else?

PLEASE NOTE: Transfers for our event on 22 June 2024 close on Monday 17 June 2024. To transfer your place to someone else you will need the confirmation email you received when you signed up. 

- Click the 'Go to my participant dashboard'

- On the dashboard page scroll down to 'TRANSFER MY REGISTRATION' and enter the email address of the person you want to take your place

- Click on 'Transfer my registration'

That's it! It is now down to the new person to complete the transfer. After completing this process your registration will be transferred to your friend. Please note, there is an admin fee to use this transfer option. Also the money for the ticket will not be automatically refunded, you will need to sort the cost of the ticket out between yourselves. Finally the cost of the ticket will be the current ticket sale price and not necessarily what was originally paid, plus the admin fee.

What does Mud Monsters Run involve?

All events are held at the Mud Monsters site in East Grinstead, West Sussex.  You can choose whether to run 7km or 14km (two laps of 7km route). It consists of a fun, challenging run through the lovely Sussex countryside, which combines fields, woods, puddles, swamps and streams with lots of challenges and obstacles along the way and of course mud, mud and more mud. At the end every runner will get a medal to prove that you made it as well as free photos to download after the day.

Entry fees

Online entries close midnight on Tuesday 17 June 2024. For details on current prices please check our pricing page here

First Aid

We always have a brilliant medical team onsite at the race providing first aid. The first aid area will be located in the event village. 


Who can compete

Pretty much anyone can compete, we welcome a wide range of fitness abilities. Mud Monsters Run is designed so that most people can get around and if you run fairly regularly then you should be fine, but it is amazing what a bit of determination can do on the actual day. Of course your safety is important to us and you may need to consult your doctor before the race. To take part you must be at least the age of 16 on race day to run on your own.

Aged 12 - 15
We have lowered our minimum age so now those aged 12-15 can run too. In order to run you must have a waiver signed by a parent or guardian and have an adult run the race with you. You must also enter any wave from 10.15am onwards. If there are any questions regarding this please feel free to send an email to


Key / Kit Storage

There will be a supervised key drop at the cost of £1 available should you need to use it. If you would like to put a larger bag into storage there will be a small charge of £3 for this. The key/bag drop will be manned by one of the charities we work with so any money paid for bag storage will all go to that charity.


Please note that the event organisers cannot be held responsible for any losses and we recommend you do not bring valuables with you.



Parking will be available at the site for £5 per car at the gate, cash only please. We will donate a percentage of this money to the charity who will be overseeing the car park for us on the day.



We will have a brilliant photography team from Epic Action Imagery with us on the day so make you’re wearing a nice big cheesy grin. All our photos will be available for free on the web after the race so make sure you keep your race number visible then the photographers can tag you, making the pictures easier for you to find.

Race numbers

You will collect your race number headbands from registration on race day. 


Food and Drink

Hot and cold food and a range of drinks will be available on the day.


Refunds – Cancellation Policy

As with most sporting events we state in our terms and conditions that we are unable to offer refunds or move you to one of our other events after you have booked and paid for your place. You can however make a substitution via your account up until 4 weeks before the run if you can find someone willing to take your place, please note there is an administration fee involved in this process and you will need to sort the money for the price of the ticket out between yourselves. We do work with a company called BEticketing (previously Circle Ticketing), where you can add insurance to your booking which will cover you in the event of illness, injury etc.

What to wear

We HIGHLY recommend you wear trail, cross country or fell running shoes which have grippy soles, these give you so much more traction on the course and greatly reduces the risk of you slipping over and injuring yourself. Moulded football boots have also been recommended in the past and are fine for the muddy areas but please be extra careful in these boots on obstacles as they will provide little to no grip when climbing etc. Normal trainers are not ideal and can be dangerous due to how slippery the course can get, you will probably get round but when they get muddy they just slip and slide which is both frustrating and can lead to accidents. Shoes that might be dangerous will not be allowed, there will be NO spikes allowed on the day our officials will be checking footwear on the day and if they are deemed to be dangerous you will not be allowed to run. 

We recommend that you wear lightweight clothes that will dry quickly, even if it’s cold as heavy or thick clothing will retain the water and not only weigh you down but also make you colder.  Long sleeves and bottoms might help protect you from scratches.  It’s also a good idea to bring a change of clothes with you so you can relax and enjoy yourself in some clean clothes after you’ve run.


Can I run for charity?

We support a number of charities which can all be viewed here. We would love it if you also chose to support one of these charities as well but if you decide to run for a different charity we will be equally as pleased. However, you do not have to run for charity.


What if the run is sold out?

If a run is showing as sold out before race day then we will no longer be able to add anyone else beforehand, this means we have reached our capacity. Our races are very popular and have previously sold out so we would recommend if you are running with friends or as a team that you get everyone to register as soon as possible to avoid people not being able to run. We do normally have on the day entries if you need to enter at the last minute. For any further information on this please email

My pre race email has not arrived

Pre race emails are sent out about 7-10 days before each event and all runners will need to collect their registration packs at the check-in tent on site on race day. You can view the 2024 Pre race Email HERE

Ninjas Pre race email can be viewed HERE

I would like to try and Qualify

We are pleased to announce that we will be an official qualifying event for the OCR Championships…that includes British, European and World. In order to be a qualifier you must sign up to the 7km in the 10am wave, which is our only competitive wave, you will be allocated a bib so you can be identified on course. You must complete all the obstacles or the penalty if you do not complete an obstacle. Your time will be noted at the finish line and results will be released the following day. The first male and female get elite qualification to the British OCR Championships and top 10 males and females get age group qualification to the European and World Championships. 


I hear you are introducing hot showers?

We are indeed! New for 2024 we will be introducing hot showers in our event village. These amazing showers are genius! The water is heated by a fire throughout the day, each person is given a bucket of hot water which hangs above you with a little tap on it, you stand in your very own little tarpaulin cubicle where you can wash off the worst of the mud and warm up so you are ready to sit down and chill out with something tasty from one of our food vendors and swap muddy stories about the run. The showers will be working on a token system, 1 token per shower, tokens can be purchased from the registration tent when you arrive in the morning, or from the shop or bag drop throughout the day. Tokens are £2.50 each and cash is preferred but we will be able to accept card on the registration desk and in the shop, the bag drop will be cash only. Please note you are not able to reserve a time slot for the showers.
