The Marathon des Sables is a six-day, 250-kilometer ultramarathon through the Sahara Desert in Morocco, widely considered the toughest foot race on Earth. Competitors carry all their own equipment and food, receiving only water and a tent to sleep in. The self-sufficiency challenge and extreme heat make it a bucket-list event for ultra runners worldwide.
