The desert, non-stop
40 hours to test yourself, push higher, and conquer the Sahara over 100 km or 100 miles.
THE CONCEPT
To celebrate our 40 years of extreme adventures, we’re launching our 40th year with a brand-new, unique format: the MDS ULTRA.
This is an endurance event in Ultra-Trail format, with two distance options — 100 km or 100 miles (~160 km) — to be completed in self-sufficiency over 40 hours of continuous racing.
On the program:
The MDS Ultra offers a raw and poetic immersion into the true spirit of ultra-distance racing.
Limited to 200 participants.
THE FORMAT
Two distances are offered:
You can decide your chosen distance up to the fork located around the 60 km mark. The course is the same for the first 60 km and the final stretch, with a single start and a shared finish line.
The MDS ULTRA takes place along parts of the legendary MDS route in the Moroccan Sahara.
It is an ultra-distance event, and gaiters are recommended.
The course is fully marked.
In January, the Saharan desert offers a stark contrast:
You’ll need gear suitable for both heat and cold, as well as potential rain.
