Series Detail


The 4 Deserts Ultramarathon Series is the world's leading endurance footrace series. A unique collection of world-class events that take place over 7 days and 250 kilometers in the largest and most forbidding deserts on the planet.

Competitors are challenged to go beyond the limits of their physical and mental endurance. Racing self-supported in the most inhospitable climates and formidable landscapes, they must carry all their own equipment and food and are only provided with drinking water and a place in a tent each night to rest.

The series, named again by TIME magazine in 2010 as one of the world's Top 10 Endurance Competitions, comprises the Atacama Crossing in Chile, the Gobi March in Mongolia, the Namib Race in Namibia and The Last Desert in Antarctica.

"To dream anything you want to dream, that is the beauty of the human mind. To do anything you want to do, that is the strength of the human will. To trust yourself to test your limits, that is the courage to succeed."

-Bernard Edmonds

Each of the 4 Deserts is completely unique. In every race competitors find themselves immersed in ancient cultures and surrounded by stunning scenery and indigenous wildlife. The 4 Deserts takes competitors on a journey through the driest, hottest, coldest and windiest places on earth, testing their limits both physically and mentally. Competitors complete the events as part of a new family -- individuals and teams from distant corners of the earth from different backgrounds, religions and cultures bonded together by a common mindset and a shared experience like no other. The 4 Deserts Ultramarathon Series is a world class sporting event open to anyone who is ready for the journey of a lifetime.

The 4 Deserts Ultramarathon Series seeks individuals and teams who are internationally diverse, open-minded and determined. We accept both elite and non-elite individuals and teams. The qualifications require that you and/or your team complete several registration and medical forms which are provided upon registration. The overall finishing times range from about 25 hours to 70 hours (combined times over seven days).
