The Belleek 10K is a single-loop road and trail race that starts near the Ballina Athletic Club and finishes at the Ballina Soccer Club in County Mayo. The course initially takes participants out onto the Killala Road and through local paved roads before entering Belleek Woods for the final 3km. The terrain features an undulating profile during the first half of the race, followed by a downhill section through the forest trails alongside the River Moy as runners head toward the finish.
