The Clare Burren Half Marathon follows a mixed-terrain route that starts and finishes on the seafront pier in Ballyvaughan. After departing the village, the course travels through the Burren National Park on a combination of paved roads, "green roads" (grass-centered tracks), and off-road trails. Landmarks along the circuit include the Burren College of Art, the ruins of Rathbourney Church, and the high-elevation sections of Poulacapple and Gleninagh. The terrain features moderate elevation gain with views of the Aran Islands and the Connemara coastline before returning to the village via the coast road.
