这项马拉松的灵感源自史上著名的越狱事件,比赛极为严峻,考验运动员的耐力和毅力。参赛者中,跑完全程的人却少之又少。In its first 25 years only 10 people have finished The Barkley Marathons. Based on a historic prison escape, this cult like race tempts people from around the world to test their limits of physical and mental endurance in this documentary that contemplates the value of pain.
