Harpeth Hills Flying Monkey Marathon Many modern marathons have become spectacles rather than athletic events. But it was not always this way. Marathons used to be about running for the sake of running. They were about pushing oneself beyond the physiologic limits of the human body. While running. Featured in Marathon & Beyond and in Runners’ World magazines, it is a marathon that is about running. Running hard. Running over big and memorable and painful rolling hills through dense woods. Running with other like-minded athletes. The Harpeth Hills Flying Monkey Marathon is about the joy and pain of running a unique, and uniquely challenging–some would say beastly–26.2 mile course in the beautiful and historic Percy Warner Park, nestled among the Middle Tennessee Harpeth Hills. Proceeds from race registrations support Friends of Warner Parks. For more information visit the Harpeth Hills Marathon website.
