Nestled within the heart of Wales, Park Farm Llangattock serves as the gateway to an epic adventure known simply as The Beast. This challenging course invites runners to traverse through a landscape rich with history and natural beauty, offering breathtaking views at every turn. The journey begins alongside the tranquil Brecon and Monmouthshire Canal before venturing into lush fields and ancient walkways. Runners quickly ascend towards the majestic Llangattock Escarpment where panoramic vistas of the Beautiful Black Mountains, Sugar Loaf, and The Brecon Beacons unfold in a breathtaking display of Welsh wilderness. Continuing southward through open moorland, participants encounter the Lonely Shepherd—a striking stone formation steeped in local folklore. Here, runners can pause to capture an iconic photo before navigating over rugged terrain with views of the Clydach Gorge’s hidden waterfalls and remnants of its industrial past. The trail then leads across Mynydd Llangattock where a descent through a picturesque valley filled with rivers and abundant wildlife awaits. This serene section transitions into ancient woods, culminating in an infamous technical incline that tests runners' agility before the final push back to Park Farm Llangattock via the canal's stone staircase. For those seeking even greater challenges, The Beast offers multiple distances including an ultra route covering 30 miles and a marathon distance. Each course features well-marked routes with essential water stations and energy zones along the way. Dogs are welcome on this adventure, adding to the camaraderie and charm of the event as they join their human companions through fields, forests, and moorlands. Runners must adhere strictly to mandatory kit requirements for safety purposes, ensuring all participants have everything needed to tackle The Beast’s varied terrain with confidence. Remember to bring your reusable cup as this is a zero-waste event dedicated to environmental stewardship. Join us in conquering the natural splendor of Wales and embrace an unforgettable journey through some of its most stunning landscapes. The event, however, has been cancelled for this year.
