Mud Monsters are renowned for their mud and the Mud Monsters Run will not disappoint. You will be taken on a journey across muddy fields, up steep hills, through woods, washing off in river crossings, navigating through craters, fighting your way through deep muddy bogs, with over 20+ obstacles to tackle and many more muddy surprises along the way. Based in East Grinstead in the beautiful Sussex countryside, we have the ideal location for what was described by one reviewer as ‘the best volume of mud I have ever experienced.’  There are three distances to choose from 5k, 10k or 20k (double lap). Every runner to cross the finish line gets a free medal, t-shirt and goody bag.
