About The Harpeth Hills Flying Monkey Marathon

Ours has become an age of flat and fast marathons on city streets and in urban jungles, with more focus on times, course certification, gadgets, charities and putting on a big show than on running. 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.

The Harpeth Hills Flying Monkey Marathon is meant to be an antidote. 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.

We will time and measure the distance, but the course will not be certified and it will not be a Boston qualifying event. If you get to the end and you (or your gadget) believe the route to be long, we won’t charge you extra; if you believe it to be short, just keep running. There will be no bands, cheerleaders, wave starts or crowds. We promise no marathon Personal Records, but we guarantee every runner a PR – a Permanent Remembrance of a well-earned marathon finish. 

We promise to give you approximately 26.2 tough and memorable miles, with a total of over 3600 feet each of elevation gain and loss, or over 7200 feet of overall elevation change.Sure, there are other road marathons out there claiming to be America’s toughest. But they are no Monkey. Come out and join us in Nashville. We look forward to seeing you.Running a Marathon in Nashville’s Percy Warner Park will allow you to; share the beauty and challenge of the Park, persevere an endurance test rather than just run another "flat and fast" marathon route, an join a bunch of like-minded people who are up for a unique, and uniquely challenging, run.

  • Open fields densely
  • Forested glades
  • Quiet picnic pavilions
  • Iroquois Steeplechase


As you wind your way through the tree-shaded Park, you endure over 1,500 feet of elevation gain and loss, encountering grades of up to 10-12% at times. Mercifully, you will also pass an occasional long, flat stretch around open fields and densely-forested glades. The route takes you by scenic overlooks of Nashville, various sports and recreation areas, and quiet picnic pavilions. You also pass the Iroquois Steeplechase, one of the country's oldest horse tracks. But above all that, with its repetitive climbs, descents and rolling terrain, Percy Warner Park demands the runner's attention and respect. The 11.2 should never be taken lightly. And the marathon will cover it twice. And it will just keep going.
