About the Event

Embrace the legendary challenge of North Wales at the Excalibur Trail Races on Sunday, May 10, 2026. Set on the spectacular Clwydian Range, this tough and beautiful event offers a true test for trail and fell runners with three iconic distances: a formidable marathon (42 km), a challenging half marathon (21 km), and a rugged 10km, all featuring significant, relentless ascent through ancient, Arthurian-steeped landscapes. The routes are a classic tour of the Range's heather-clad peaks, offering breathtaking views and demanding climbs that will push your endurance and reward you with a profound sense of achievement. More than just a race, it's an event with a powerful purpose, organized by and in support of Running Head First CIC, a not-for-profit dedicated to improving mental and physical health through community running, meaning your entry directly contributes to vital local programs. With its raw, authentic fell-running character, stunning scenery, and a deeply supportive, community-focused ethos, Excalibur is a must-do for any serious trail runner seeking a meaningful challenge. Whether you're conquering the full marathon or testing your mettle on the 10km, you'll be part of a special day that celebrates both personal resilience and collective good in one of Wales' most dramatic landscapes.
