There is a half marathon in Westport, Mass that you might be interested in running. The course is mostly flat and the scenery is pretty stunning.
http://horseneckhalf.com/registration-details/I havn't run it yet myself but I'm very familiar with the course having lived in Westport for the past 20 odd years. I've either run or biked these roads for decades. You get your typical gorgeous coastal New England ambience here. I havn't personally signed up for this yet myself, but I'm leaning towards doing it. You know, just for the shirt and post race beer.
