Cast your mind back to the halcyon days of open fields, muddy ditches, ill-fitting shorts and steam rising from your singlet: This is Cross Country Running as it always was, but not quite as you remember it. Because this is a classic off-road mud run re-invented especially for the 21st century, carefully crafted from the Rat Race Old Skool Gym Locker.

Our PE lesson is simple: Join us at a brand new venue – Claydon Estate, never before used for a running event. On our whistle, prepare to run 5 miles (or 10, if you want 2 laps) under the supervision of our Games Masters on a classic traffic-free fully off-road X-country loop.
