Runners follow an out-and-back course for both races at Dublin’s Emerald City Half Marathon, which starts and finishes near Dublin Methodist Hospital, just off Perimeter Drive near the Avery Square shopping center. From there, runners head north through the Honda Wetland Educational Area and through the park roads of Glacier Ridge Metro Park, a 250-acre restored wetland area just outside downtown Dublin, before heading back to the hospital for the race finish.
