The Marathon des Sables is a multi-stage, self-sufficient ultramarathon held annually in the Sahara Desert in Morocco. The 40th edition of the race is scheduled to take place from April 10 to April 20, 2026. Participants must carry all their own food and equipment for the duration of the event, with only water and a traditional Berber tent provided by the organization.
The classic format of the race covers approximately 250 kilometers (about 155 miles) over six stages. The stages vary in length, with the notorious long stage historically extending to around 90 kilometers. For the 2026 edition, organizers have announced that the long stage will be a 100-kilometer (62-mile) trek, making it one of the most demanding segments in the event's history.
Beyond the main race, the event offers other experiences. These include a non-competitive 'Trek' format designed for participants seeking the adventure without the competitive pressure of the ranking. The organization also frequently highlights the unique and challenging 'loops' and dune sections that define the course's character, testing runners' endurance and navigation skills in extreme heat and terrain.
The Marathon des Sables was founded by Patrick Bauer and first held in 1986. It has grown into one of the world's most famous and grueling footraces, attracting thousands of applicants from over 50 countries each year. The 2026 edition marks a significant milestone for this legendary endurance challenge.
