London Obstacle Races

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 120+ obstacles and many more muddy surprises along the way.

This run takes place on Sunday 03 June 2018 at our permanent 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!

Gung-Ho! is an inclusive 5km running event, with a focus on fun and it's coming to London in 2019 on 13th July. Get ready to run, jump and climb over some of the biggest inflatable obstacles in the world and show how Gung-Ho! you really are!

Step Outside Your Comfort Zone
