The Macroom Castle Demense parkrun begins and ends outside the Community Leisure Centre, just inside the town’s impressive castle gates. This varied 5k course starts with one lap around the local GAA pitch before transitioning into two scenic loops through the historic Castle Grounds. Participants follow a route that passes the Macroom Golf Club, winds along the banks of the Sullane River, and heads toward the iconic "Black Gate". The terrain is a mixture of permanent tarmac and gravel paths, ensuring a reliable surface through the changing seasons. While there are several flat stretches, the course is characterized by its undulating profile, featuring a short, steep hill near the water works that runners must conquer twice.
