The elevation is one of the most notable challenges of the race. (Add in the fact that it’s easy to go off course, and you can see how it becomes longer.) The distance for each is about 20 miles, according to Cantrell, though runners often dispute the claim saying it is roughly a marathon.

You must complete five loops of the course to earn the title of Barkley Finisher. From there, all you need to know is it takes you through the park’s more than 24,000 acres, by the closed Brushy Mountain State Penitentiary, and up and over wicked terrain and switchbacks.

The course is not well-known outside of those who have attempted a loop of the fabled race, but for your main reference you should know it takes place in the Cumberland Mountains within Frozen Head State Park, which is in Wartburg, Tennessee.
