When do registrations for an MDS edition close, and when do registrations for the following edition open ?

Registrations for our MARATHON DES SABLES do not close on a specific date, but as soon as the event reaches full capacity. This means there is no predefined deadline.

Therefore, if you wish to participate in a specific edition, we recommend not waiting too long to finalize your registration.

In the case where a destination is about to reach maximum capacity, we always inform participants a few days in advance, both through our social media and via our newsletter (if you're subscribed).

As for registrations for the following year's editions, they generally open several months before the start of the event.
The official announcement is made a few days in advance, always via our social media and newsletter, to give you time to prepare and register under the best possible conditions.

We therefore recommend keeping a close eye on our communication channels so you don’t miss any registration openings or closures !
