Trails & Tarmac Back Yard Ultra - Summer

Test your ultimate endurance against the clock and the competition in the unique Trails & Tarmac 12hr Backyard Ultra, set in the beautiful Black Mountains of Wales on Saturday, 19th September 2026. This innovative event blends the classic backyard format with a thrilling final twist: after 11 standard 4.2-mile loops, the 12th and final loop is run in reverse as a decisive sprint to crown the winner. The fast, 50/50 trail and tarmac course with minimal climbing near Crickhowell means you can maintain a relentless pace, fueled by hot food and a supportive atmosphere. Organized by the passionate local runners of Limitless Trails, it's more than a race—it's a community battle of will where the last person standing claims the trophy, and everyone reaching the 32-mile ultra distance earns a unique 2026 finisher's medal. With camping on-site, recovery sauna options, and a professional yet friendly vibe, it's the perfect late-summer challenge to push your limits in the heart of Wales.
