That is the equivalent of climbing up and down Mount Everest twice. Once a competitor has started a loop they are not allowed to receive any assistance until they have finished that loop. Runners must ascend and descend about 120,000 feet of elevation. That is a 12 hour cut off time per loop and there are five loops. You have 60 hours to complete the entire course. The race distance choices are a 97km ‘fun run’ or 160km for the full course.

Here are 10 reasons why the Barkley Marathons is the most ballistic thing on earth (in a good way!). Only the truly tough ultrarunners would even consider it and even then they may not get in if their penmanship is not good enough! Held in Frozen Head State Park in Tennessee, it’s quirky, it’s insane, and it’s just downright brilliant.

This is an ultramarathon trail race like no other.

It is a race you may have heard of from the documentary on Netflix, The Barkley Marathons – The Race That Eats Its Young. On the first week of April (around April Fool’s Day) every year a flock of 40 hardcore ultrarunners gather in the Appalachian mountains for the notorious fringe event known as The Barkley Marathons. If you are an avid ultrarunner, you will definitely have heard about this insane ultra in Tennessee, The Barkley Marathons.
