Organiser's Description
Mud Monsters Run have three different distances for you to pick from – 5km or 10km (double lap) or our brand new Mini Monster 3km lap for newbies and anyone who fancies a taster of the course. Whichever you choose you will be taken on an amazing, fun 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 an obstacle packed course and many more muddy surprises along the way.
This run takes place on Sunday 17 May 2026 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 around 9.30am and go regularly throughout the day, we limit 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 tougher challenge then the 10km route is for you this is two laps of the 5km course and will provide an extra muddy challenge if you want a longer distance.
If you are a newbie or just want to give the course a go but would prefer a shorter distance we have our BRAND NEW 3km our Mini Monster route for ages 10 plus, although under 16's will still need to run with an adult, spaces in this special distance will be really limited to make sure you book up soon to avoid disappointment.
Anyone from the age of 12+ can run in the 5km, please note 12-15 years olds must run with an adult at all times, the maximum distance they can participate in until they are 16 years old is 5km.
