About the Event

Tame the wild heart of Wales on an adventure that matches your ambition. The Beast of the Beacons on Saturday, 18 April 2026, presents three iconic distances—10, 20, and 40 miles—carved into the majestic and demanding trails of the Brecon Beacons National Park. Starting and finishing at Gilestone Farm, each route is a spectacular journey through mountains, forests, and past serene reservoirs, offering harsh climbs, rocky paths, and breathtaking vistas where red kites soar overhead. With generous cut-off times and a famously supportive atmosphere, the event welcomes elite runners, determined first-timers, and even canicross teams. Expect fully stocked checkpoints, handcrafted Welsh slate trophies, and a vibrant festival finish with local catering. This is more than a trail run; it's a raw and rewarding celebration of the Welsh wilderness. Choose your challenge and test your spirit against the Beast.
