Boston by Segway (departure 2.4 miles)
Warning: This is a tour best saved for after the race. For runners who finish with legs and feet that can handle standing for long periods of time, a Segway ride is ‘‘a unique way to enjoy the city at a pedestrian level,’’ said Allan Danley, director of operations. Segway operation requires little movement besides slight shifts in weight forward or backward. Tours run one to three hours. The one-hour tour features Boston Harbor and attractions in the Seaport District. On a three-hour tour, riders travel 22 miles and see most of the city, including the Back Bay, Theater District, and North End. Tours start with 20-minute training sessions.
