Marathon Des Sables
Sand, dust and sweltering temperatures in the Sahara desert greet marathoners

The Marathon de Sables is a six-day, 251 km run through the dreaded Sahara desert in southern Morocco. If the length of the course doesn’t intimidate you, the fact that it’s a 251 km run through a scorching desert, that will. It is officially classified as an ultra marathon.

What makes this course such a challenge it that the sand is so fine that runners’ feet literally sink into the ground, which seriousl hampers progress, while on the hardpan surface the one thing to worry about is the soaring temperature, so there is virtually no part of the marathon that goes easy on the competitors.

This marathon is so treacherous that at one point 3 runners died en route.
