Midlands Mud Run

About this event

Belvoir Castle might look majestic, but the historic estate grounds do not play fair for 2027. Located in Grantham, this course swaps postcard-perfect views for a massive, energy-sapping battlefield, cementing its spot as one of the most technically difficult events on the entire UK calendar. Expect killer Midlands hills, plenty of incredibly muddy tracks, and scenic views of the castle. All of the obstacles are up-scaled for this event with a number of tweaks and surprises in store due to the varying, unforgiving terrain. The ground here holds water like a sponge, transforming the dirt paths into a heavy, suction-heavy sludge that will weld itself to your boots and pull your shoes clean off your feet. Everyone else across the Midlands and beyond is already booking their start times, coordinating their teams, and snapping up the choice early-morning waves for the 5K and 15K courses. Secure your start wave today and bring your bravest energy; otherwise, you will spend the weekend muted on the group chat, scrolling through everyone else's finisher photos from your couch with serious regret.
