The Harpeth Hills Flying Monkey Marathon is a 26.2-mile (42.2 km) road race in Percy Warner Park, the larger of the Warner Parks in Nashville, Tennessee. It was created to be among the top five most difficult road marathons in the United States, and was designed to be somewhat anti-establishment and grassroots in character. In particular, the Harpeth Hills Flying Monkey Marathon is consciously not part of any running series and is neither certified nor sanctioned by the USATF, but is the standard 42.195 kilometres (26.219 mi) . A runner cannot use this race to qualify for the Boston Marathon. This marathon was initially dreamt up by a broad array of Middle Tennessee runners and was first described on an internet message board dedicated to Middle Tennessee runners. The original organizers included Trent Rosenbloom, The Nashville Striders, Peter Pressman, Diana Bibeau, and others. Wikipedia
