The Marathon des Sables is a legendary 250km, six-stage ultramarathon through the Moroccan Sahara, widely considered the toughest footrace on Earth. Participants must be self-sufficient, carrying all their food and equipment while navigating extreme desert terrain and temperatures.
Course Highlights
The legendary course spans approximately 250 kilometers of the Moroccan Sahara, starting and ending near the host city of Ouarzazate. Runners traverse a punishing variety of desert landscapes, including vast sand dunes (ergs), rocky plateaus (djebels), and dried-up riverbeds (oueds). The elevation profile includes significant climbs, such as the ascent of Jebel Irhs, which offers sweeping desert vistas. The “Long Stage” (Stage 4) typically exceeds 80 kilometers, requiring overnight navigation through soft sand and technical terrain under the stars. The route is kept secret until days before the race, concluding at a jubilant finish line that celebrates the completion of six grueling stages.
Why Runners Love It
Often called the “toughest footrace on Earth,” the Marathon des Sables is iconic for its requirement of total food self-sufficiency in one of the world’s harshest environments. Runners must carry their entire week’s supplies, while the organization provides only water and open-sided Berber tents. This unique logistical challenge, combined with Saharan heat and the legendary 80km “Long Stage,” creates a profound test of mental and physical fortitude. The race is famous for its “MDS family” atmosphere, where 1,200 participants from 60 nations bond over shared hardship and breathtaking desert landscapes, making it a pinnacle achievement in ultra-running.

Race Weekend Tips
Arrive in Ouarzazate at least a day early to acclimate to the Moroccan heat and organize your gear at the Hotel Karam Palace HQ. During the technical check, ensure your pack weight is optimized between 6.5kg and 8.5kg for the best balance of safety and speed. Professionally sewn gaiters are essential to keep fine sand out of your shoes. Pack high-calorie luxury snacks for the first two stages to boost morale, and bring a high-quality, lightweight sleeping mat to survive the rocky bivouac ground.
History & Charity
Founded in 1986 by French concert promoter Patrick Bauer after a solo Sahara crossing, the Marathon des Sables has grown into a world-renowned endurance icon. The race is managed by Atlantide Organisation Internationale and operates the “Solidarité Marathon des Sables” association. This charity funds the MDS Sport-Health Center in Ouarzazate, which provides education, sports, and healthcare for local children and women. Since its inception, the event has balanced its extreme reputation with a deep commitment to environmental preservation and community development within the Drâa-Tafilalet region.
