The Westport Half Marathon follows a scenic out-and-back paved route that starts and finishes at Westport Quay (Roman Island), offering a picturesque journey along the shores of Clew Bay. The course travels through the historic Westport Railway Walk and along the sheltered Greenway, with the imposing peak of Croagh Patrick providing a constant backdrop. The terrain features some rolling coastal sections and steady drags typical of the Wild Atlantic Way. Runners navigate a well-marshaled circuit through the village of Murrisk and past the Famine Memorial Park before returning for a celebratory finish near the Towers slip road.
