Marathon des Sables stage maps and checkpoints

About 250 km across the Moroccan Sahara in six stages, carrying your own food and kit. The route is a secret until you reach the bivouac.

April 2 to 12, 2027 Sahara, southern Morocco

The MDS Legendary is the original Marathon des Sables, held in the Sahara since 1986. You cover about 250 km in six stages over seven days, running or walking, and carry everything you need except water and your tent. The whole trip is 11 days in Morocco, nine of them in the desert. The 41st edition runs April 2 to 12, 2027.

There's no GPX and no published route. The course can change from year to year, and the organizer hands out the roadbook at the bivouac two days before stage 1. The maps here are the 2026 route, the 40th edition, with every checkpoint placed from the race's own timing data. It started in the open desert near Tafraout Sidi Ali, in Errachidia province, and finished on the western edge of Erg Chebbi, about 3 km north of Merzouga.

Use it to see the kind of ground the race picks and how far apart the checkpoints sit, knowing the 2027 route can be different.

Stage 1 ran on April 5, 2026, starting at 7:00 AM with a maximum arrival time of 5:00 PM. It left the first bivouac heading west, turned at CP2, and came back east to finish where it started, so you slept in the same camp again. Climbing was 285 m over 35 km.

MDS Stage 2 (2026)

The first move east: 40.5 km to the second bivouac, with five checkpoints.

Stage 2 started at 6:00 AM on April 6 and closed at 5:35 PM. It headed east the whole way, past the village of Ramlia, to a new bivouac about 10 km beyond it. The checkpoints came every 5 to 8 km after the first one at 10.9 km, with 486 m of climbing.

Stage 3

MDS Stage 3 (2026)

A shorter 29.1 km loop from the second bivouac, three checkpoints.

For the 40th edition the long stage was 100 km with 721 m of climbing, longer than the usual 80 km or so. It started on April 8 at 5:00 or 7:00 AM, the race leaders in the later wave, and runners had until 9:00 PM the next day. The 2026 rules had you switch on your headlamp from 7:00 PM.

The route zigzagged north, then turned east to a bivouac about 11 km northeast of Taouz. The first checkpoint was 12 km in, and the other ten came every 7.5 to 10.3 km. The program sets aside the second day for finishing the stage and resting in camp.

Registration

Places go in the order people register, and both 2027 offers were sold out when this page was checked. You can join the waiting list on the event page, though it doesn't guarantee a place.

The Classic offer is €3,990 with two hotel nights in Ouarzazate after the race, and the Superior offer is €4,390 with the two nights at the Berbère Palace. Both include the bib, eight nights in the bivouac, water, medical support and postponement insurance. Cancellation is free until August 31, 2026, then costs 25% of the fee through October and 50% through December. After December 31 there's no refund, but you can still postpone free until March 26, 2027.

Minors can't enter. You'll need the organizer's medical certificate and a resting ECG with its tracing, both originals, dated no more than 30 days before the start.

Getting to the bivouac

Everyone gathers in Ouarzazate. You can fly there directly, though there are fewer flights, or into Marrakech, where the organizer runs transfers to Ouarzazate on the mornings of March 31 and April 1, 2027. That drive is five to six hours. Arrive no later than April 1, and book your nights in Ouarzazate before the race yourself.

On day 1, buses take you into the desert to the first bivouac. After the last stage they bring you back to Ouarzazate for two hotel nights and the gala. The return buses to Marrakech leave at 6:00 AM on April 12, so book a flight home from Marrakech after 2:00 PM.

Water, food and kit

The organizer gives you water and a place in an open-sided eight-person Berber tent, grouped by country. Everything else is on your back. Checkpoints come roughly every 10 km and hand out water. At the end of each stage you get 5 liters, which has to last the evening and the next morning until the first checkpoint. Water from anywhere else is banned.

Carry at least 2,000 kcal for each race day, 12,000 in all for 2027, repacked with the calories written on it, because it's checked. Gas stoves are not allowed. The mandatory kit includes a sleeping bag, a 400 lumen headlamp with spares, 1.5 liters of water capacity, a compass, a signalling mirror, a survival blanket, a knife, two stock cubes per race day, 50 ml of sunscreen, your passport and €200 or 2,000 dirhams. With food, your pack has to weigh between 6.5 and 15 kg, not counting water.

Weather

The nearest long-term normals are for Errachidia, the provincial capital north of the 2026 course, a town at 1,009 m. In April it averages highs of 26.1°C and lows of 13.0°C (NOAA, 1991 to 2020), and its hottest April day in those 30 years reached 34.9°C. The 2026 bivouacs and finish sat lower, at 630 to 710 m, so expect it warmer on the course.

The regulations warn of heat, cold nights, wind and sand. Pack for both ends: something warm for the bivouac and protection from the sun all day.

MDS FAQ

When is the Marathon des Sables 2027?

The 41st MDS Legendary runs April 2 to 12, 2027. The program puts the transfer to the bivouac on Friday April 2, stage 1 on Sunday April 4, the long stage on April 7 and 8, and the last stage on Saturday April 10.

Is there a GPX of the Marathon des Sables route?

No. The route can change from year to year and is only in the roadbook, handed out at the bivouac two days before the start. The maps on this page are the 2026 route, from the organizer's timing data, not 2027's.

How long is the long stage of the MDS?

Usually about 80 km, spread over two days, the second of them for finishing and resting. For the 40th edition in 2026 it was 100 km with 721 m of climbing and a 40 hour limit. The regulations say it isn't always stage 4.

Can you walk the Marathon des Sables?

Yes. The organizer says over 30% of entrants walk, and the cutoffs are set at 3.5 km/h so walkers can finish. The average pace is 5.2 km/h, and about 90% finish.

How much water do you get at the Marathon des Sables?

Water at each checkpoint, roughly every 10 km, and 5 liters at the end of each stage to cover the evening and the next morning until the first checkpoint.

Can you use your phone during the Marathon des Sables?

Not to get help. The regulations ban any phone or messaging use that brings outside assistance or race information. GPS watches and recorders for your own use are allowed. There's nowhere to charge, so bring your own power. The organizer bills the trip as 11 days of disconnection.
