The Windmill Run 10k follows a single-loop paved course that starts and finishes in Garristown, North Co. Dublin, serving as the official Dublin 10k Road Championships. The route travels through quiet rural townlands on marshaled country roads, offering expansive views of the historic landmark windmill. The course features an undulating profile with several steady, rolling drags before a fast, mostly downhill final two kilometers leads back into the village center.
