Dive into the rugged beauty of Wales with The Beast of the Blacks race series. Offered in 10-mile, 20-mile, and an epic 40-mile distance, these trails wind through the majestic Black Mountains, offering a blend of challenging terrain and breathtaking vistas for runners of all levels. The journey begins near Llanbedr village, where you'll ascend directly into the heart of the mountains. The route is marked with vibrant forest paths, rocky summits, serene river crossings, and historic churches dotting the landscape. Red kites soar overhead alongside a diverse array of wildlife, adding to the wild charm of this adventure. For those tackling the full 40-mile course, you'll experience each section twice as the second half retraces your steps from earlier in the day. This unique feature allows runners to appreciate any missed details or scenery on their return journey. Supportive marshals and generous cut-off times (5 hours for 10 miles, 8 hours for 20 miles, and 16 hours for 40 miles) ensure that all participants have ample time to navigate the challenging terrain. Whether you're an elite runner looking to push your limits or a beginner seeking an unforgettable experience, The Beast of the Blacks promises an invigorating day in one of Wales' most captivating natural settings. Canicross enthusiasts are welcome too, with dogs aged 12 months and older joining their human companions on lead throughout. While runners can compete for awards, those participating with their canine friends will focus purely on enjoying the stunning mountain landscapes together. Join us to explore the wild beauty of Wales during one of its most enchanting seasons—Spring.
