About the Event

Confront the ultimate Lake District challenge at the Altra 13 Valleys Ultra, September 25-27, 2026, a monumental three-day trail running odyssey that connects all 13 iconic valleys of the UNESCO World Heritage landscape. Choose your epic: the staggering 184km 13 Valleys route with 7000m of ascent, the 110km 7 Valleys, the 55km 5 Valleys, or the accessible 22km 2 Valleys Trail—each meticulously crafted to showcase the raw beauty and brutal grandeur of England's most celebrated mountains. This is a true navigational adventure on unmarked, world-class trails, demanding self-reliance and resilience as you traverse pristine lakes, high passes, and remote fells far from the tourist tracks. In partnership with the Lake District National Park, the event is a profound celebration of this protected landscape, with 5% of every entry directly funding environmental conservation projects. Whether you're an elite ultra-runner seeking a crown-jewel British challenge or a dedicated trail enthusiast stepping up to a multi-day adventure, 13 Valleys delivers an unforgettable, bucket-list experience. Secure your Saver entry for a late-September weekend where your effort becomes part of the landscape's legacy, and finishing is a legend-making achievement.
