Celebrate 53 years of the Enders YMCA Harrisburg Marathon, Half & Relay with us! The queen-mother of all running events in the greater central Pennsylvania area, this Boston-qualifier has been affectionately dubbed the “Mini-Boston” — not just in being a stepping stone to one of the most prestigious races in the country, but because Harrisburg’s heart comes alive as thousands of runners and spectators cheer you on throughout the course all the way to the finish line. This fast, flat marathon winds through urban street, forested paths, across bridges, and through natural features unique to Pennsylvania’s capital city on the river.
