About this race
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.
Course profile & record eligibility
World Athletics record-eligibility rules cap net elevation loss at 1m per km of race distance, and require the start and finish to be no more than 50% of the race distance apart — both meant to stop a course gaining an unfair edge from downhill grade or a point-to-point tailwind. This is based on this course's recorded elevation and GPS data, not an official measurement or certification.
