The Noel McManus Memorial 10k follows a single-loop paved route that starts and finishes within the historic Lough Rynn Castle estate in Mohill, Co. Leitrim. The course departs from the castle grounds to navigate the quiet, scenic roads of the surrounding countryside, offering a longer circuit than the 5k event. The terrain is known for its picturesque scenery but features a challenging profile of rolling hills and steady drags. Participants pass through the estate’s parkland and the local village area before returning for a finish at the castle.
