Runners start the out-and-back course for the Portsmouth Half Marathon in front of the Mercedes-Benz of Portsmouth dealership on Portsmouth Avenue. From there, the race first makes a loop around Greenland Road and then passes the starting line again, before heading north for a long stretch along Newington Road. This will take you north toward the town of Newington, where you’ll make your way to the Old Town Hall before turning around and heading back to Portsmouth, where you’ll cross the finish line back near the Mercedes-Benz dealership.
