About Us

Since 1986, the MARATHON DES SABLES has been crossing the world's most beautiful deserts with several concepts: the MARATHON DES SABLES THE LEGENDARY (252 km in the Sahara Desert in Morocco), the MARATHON DES SABLES (70, 100 or 120 km over 3 stages) and the new 2024 concept, the MDS TREK (4 stages with a total distance of up to 120km).
