Take on our legendary mud and #getdirty
Mud Monsters Run have three different distances for you to pick from – 5km, 10km or 20km (double lap). Whichever you choose you will be taken on an amazing muddy journey across muddy fields, up steep hills, through woods, washing off in river crossings, navigating through mud craters, fighting your way through deep muddy bogs, with up to 100+ obstacles and many more muddy surprises along the way.
This run takes place at our site in the beautiful Sussex Countryside just 5 minutes from the centre of East Grinstead (RH19 4RR – see below for full address and map). The start waves begin at 10am and go every 15 minutes well into the afternoon, we restrict the number of runners per wave so make sure you sign up to your preferred time before it sells out!
The great thing is we have so many obstacles that you never have to run very far before taking on a new and exciting obstacle challenge. We welcome people of all abilities and experience, whether you regularly compete in obstacle races or are thinking of making this your first one, just pick the distance that is right for you. We are a friendly run that offers encouragement and positivity not punishments, we want everyone to have loads of fun and achieve personal goals along the way, whether it’s beating a previous time, completing the monkey bars, scaling the vertical wall or working as a team to get around the course together.
If you are after a tough OCR then the 20km route is for you, we see the 20km claim many a seasoned OCR runner, will you be victorious or will our energy sapping, shoe sucking, legendary mud get the better of you...!?! The 20km is a challenging run and part of the challenge is making it to the halfway point in time. Every 20km runner will be moved to as early a wave as possible (whether running with a team or not), you have to be at the halfway point by 13.30 pm to start your second lap, if you are not back by this time you will not be able to continue.
Anyone from the age of 12+ can run, please note 12-15 years olds must run with an adult at all times, the maximum distance they can participate in is 10km and they must register for a start wave from 11:00am or later.
