Sliabh Liag Adventure Race

The Sliabh Liag Adventure Race delivers a tough, scenic challenge on Ireland’s highest sea cliffs. Starting at sea level, the course follows the Pilgrim’s Path, climbing nearly 600 meters above the Atlantic. Runners and hikers navigate steep ascents and rugged trails with sweeping views over Donegal Bay. Participants can choose from four distances: 5km, a steep uphill challenge; 13km, a mix of technical running and hiking; 25km, a demanding route that qualifies for the UTMB Index Race system; and 50km, an ultra-distance test with 2,000 meters of elevation gain. The 25km and 50km races offer competitors the chance to earn UTMB Index points for international trail-running events.
