The Lahinch Half Marathon follows a scenic loop starting and finishing on the iconic Lahinch Promenade. The entirely paved route travels along the Liscannor Road, offering views of the Atlantic coastline before winding through Liscannor village and the surrounding Clare countryside. The course features a mix of level coastal stretches and rolling hills as it traverses rural roads along the Wild Atlantic Way. While the terrain is undulating, the path remains straightforward and accessible for runners seeking a scenic endurance challenge. The run concludes with a return to the seaside town for a finish right by the water's edge.
