Dublin City Half Marathon 2026

The Dublin City Half Marathon begins in the heart of the capital on O'Connell Street and follows a single-loop route that showcases the city’s vibrant Northside neighborhoods. Runners depart from the historic GPO, navigating broad urban avenues and iconic city-centre streets before looping back to a grandstand finish in the heart of Dublin. The terrain is notably flat and fast, making it an ideal choice for participants chasing personal bests on a smooth tarmac surface. With energetic support from local residents and a traffic-free circuit, the course offers a unique perspective of Dublin's urban landscape.
