Charlton Park (www.charltonparkestate.com) is the spiritual home of Monster Race. This is the South Wests biggest and best obstacle course and mud run event. It’s ideally located close to Bristol, Swindon, Bath and Cardiff and the rest of the South West.

It’s a stunning country estate in Wiltshire. It is the home of The Earl and Countess of Suffolk and Berkshire who kindly let us convert their grounds each year to one of the best obstacle course races on the calendar!

It’s a perfect venue to host Monster race. Featuring 4,500 acres of land (including 300 acres of woodland) the estate has more trails, mud and water than you can shake a stick at. It also features the original Bog of Eternal stench….oh yes!

Add into the mix the Monster’s obstacles (see the obstacle page for details) and you have one of the most fun obstacle course races you will come across.
