The Medieval Marathon begins on High Street at the Tholsel, where runners depart from the heart of the city's historic center. The route initially weaves through Kilkenny’s narrow medieval streets, passing iconic landmarks such as Kilkenny Castle and St. Francis Bridge before transitioning onto the scenic country roads toward the Callan area. This course offers a blend of architectural history and lush rural landscapes, featuring a terrain that is characterized by gentle, rolling gradients rather than steep inclines. After completing the countryside loop, participants return to the city center for a spectacular finish in front of the Butler Gallery or along The Parade.
