The HMDS can be done in 2 different distances:

  • 120 km
  • or 100km

When registering, each participant may choose one of the distances. If, before the race, you wish to change for another format, this will be possible.

No matter which distance you choose, the adventure will remain the same. The only difference will be on the second stage, where the participants having chosen the 100km distance will do one loop less.

Exact distances of the 3 stages of the HMDS are kept secret until the day of arrival, where participants will discover them in the road book.

That being said, you will find below the approximate distances of each stage:

  • Stage 1: About 25/30 km
  • Stage 2: About 55/60 km
  • Stage 3: About 25/30 km

Regarding the positive elevation gain of the HALF MARATHON DES SABLES, it can be slightly different every year, but generally remains around 2500-3000 meters of m+ cumulated over the 4 days of adventure.

Whether it is on the 100 or 120km distance, you can run, but you can also walk the whole distance, as a majority of participants do.

The time barriers of the HALF MARATHON DES SABLES are very wide, allowing a maximum number of people to complete the stages in the allotted time. The minimum speed allowed is 3.5km/h.

Over the past editions of the HMDS, the average speed of participants has been 5.5km/h.
