Marathon de Sables and Badwater 135 are considered to be two of the hardest races ever. The first takes runners 156 miles through the Moroccan Sahara. The other involves 135 continuous miles from Death Valley, the lowest point in the United States, to the trailhead for Mount Whitney, the highest point in the United States. Both courses are famous for their alien landscapes and hostile temperatures.
This video follows 2014 Badwater champion Harvey Lewis as he runs the Marathon de Sables, and five-time Marathon de Sables winner Mohamad Ahansal on his first attempt at Badwater.
