The Border Half Marathon is a single-loop road race that starts and finishes at the Sean Choill Sports Complex in Corbally, on the outskirts of Limerick city. The course navigates quiet, paved country roads through the village of Corbally and continues into County Clare toward Clonlara and Doonass, featuring a scenic crossing of the Decourcy Bridge with views of the Ardnacrusha power station. The terrain follows an undulating profile, consisting of rolling sections throughout the rural circuit.
