Every year, a few thousand runners commit to the Marathon des Sables and immediately face the same problem: how do you train for a multi-stage race across Saharan sand when you live in Manchester, Munich or Minneapolis?
Treadmills with incline settings do not replicate soft sand. Beach sessions help but a beach is flat and the air is humid. Indoor adaptation protocols address climate but not terrain. The single most effective thing an MDS entrant can do, and the thing coaches consistently recommend for anyone who can arrange it, is to spend a block of days running on the actual terrain the race crosses.
That terrain is here. The Marathon des Sables routes have repeatedly crossed the region between M’Hamid El Ghizlane, the Erg Chegaga and the dry bed of Lake Iriki. Umnya Desert Camp sits inside that landscape, 40 kilometers west of M’Hamid in the heart of the Erg Chegaga. Runners who base themselves at the camp are not training on terrain that resembles the race. They are training on the race’s home ground.
Why this exact location matters
The MDS is famous for variety within brutality. A stage might open on hard hamada plateau, cross a dry riverbed of loose gravel, climb a dune cordon, and finish on a cracked lake bed. Each surface demands a different gait, cadence and mental approach, and the race punishes runners who have only trained on one of them.
Within running distance of the camp, all of those surfaces exist:
- Big dune lines. The Erg Chegaga is a 40 kilometer band of dunes reaching around 60 meters, the largest wild erg in Morocco. Dune climbing, ridge running and soft descents can be trained here at every difficulty level.
- Hamada. North and west of the erg, flat rocky desert stretches for tens of kilometers. This is where long steady-state efforts happen, the surface closest to most MDS stage mileage.
- Lake Iriki. The immense dry salt lake southwest of the erg offers dead-flat, firm crust for tempo work and a psychological experience, featureless space in every direction, that mirrors the mental load of long race stages.
- Dry riverbeds and feche-feche. Sections of powder-fine sand that swallow ankles teach the specific patience the race requires.
You cannot assemble this combination in Europe. You can barely assemble it anywhere else in Morocco. If you are comparing desert regions, our guide to Erg Chegaga versus Erg Chebbi explains why this side of the Sahara is wilder, quieter and closer to the historic race corridors.
The training camp format
Most runners come for 4 to 7 nights, either solo, with a coach, or as a small group of race entrants sharing costs. The camp has 8 tents for a maximum of 16 guests and takes full buy-outs, so a running club or a coached squad can privatize the entire site and turn it into a dedicated performance base.
A typical training day looks like this:
Dawn session. Runners leave camp before sunrise for the main quality session: dune repeats on the cordon behind the camp, or a long run across the hamada with a support vehicle shadowing the route. Sunrise over the erg is not a small bonus. It is the reason many athletes say the block felt like a privilege rather than a grind.
Recovery block. Breakfast, stretching, shade, sleep. The camp’s tents are proper beds with real linen, not race bivouac conditions, which matters: the goal of a training block is to absorb load, and absorption requires sleep quality.
Second session. A shorter technical session in the late afternoon: soft sand drills, pack-weight hiking, ridge navigation, or an easy shakeout on the lake bed.
Evening. Dinner cooked by the camp team, kit admin, and a sky that reaches Bortle Class 1 darkness. Several runners have told us the nights alone justified the trip.
The staff of 12 handles everything around the training: meals adapted to athlete requirements, water and electrolyte logistics on long routes, vehicle support so that no session ever ends with a runner stranded, and route briefings from guides who grew up navigating this desert.
Acclimatization stays before the race
The second use case is the pre-race stay. Runners flying in ahead of the MDS use the camp as a final acclimatization base: a few days of easy running on sand, dialing in gaiters, socks and pack setup on real terrain, adjusting sleep rhythms, and arriving at the start line already adapted to the light, the dryness and the feel of the ground.
There is a meaningful difference between a runner whose first contact with Saharan sand is stage one, and a runner who has already done six relaxed sessions on it. Gaiter failures, sock choices and pacing misjudgments get discovered and fixed at the camp instead of at kilometer 30 of the race.
Practical notes for pre-race stays:
- Getting here. The camp is reached via Ouarzazate and the Draa Valley. See the full route guide in how to get to Erg Chegaga. Foum Zguid, a frequent MDS logistics town, is connected to the camp by the Iriki piste.
- Transfers. We arrange 4x4 transfers from Marrakech or Ouarzazate, and the drive itself, described in our Marrakech to Erg Chegaga journey guide, doubles as terrain reconnaissance.
- Kit testing. Bring everything you plan to race with. The dunes behind camp are a complete test bench.
When to come
The camp operates September through June, which aligns perfectly with the MDS calendar. The race traditionally takes place in spring, which makes two windows especially valuable:
- October to February: the big training block. Winter in the Erg Chegaga means crisp mornings, warm clear days and cold star-filled nights. It is close to ideal running weather, cool enough for serious volume, sunny enough to bank light exposure that northern European winters deny you. This is when coached groups book multi-day camps.
- The weeks before the race: acclimatization. Spring days are warm and bright, exactly the adaptation stimulus a race entrant wants in the final approach.
Support runs and crew
Not everyone at a training camp is racing. Partners, coaches and crew members stay in comfort while athletes train, and the camp’s activity range means non-runners have their own program: camel treks, 4x4 excursions across the dunes, stargazing and Berber cooking. A training block does not have to be a family sacrifice.
For coached groups, the full buy-out format is the strongest option. Sixteen beds, a private dining tent for briefings and video review, vehicle support for point-to-point long runs, and zero strangers. The camp effectively becomes your team’s performance facility for the week. Details on privatization are on our private and exclusive page.
What runners take home
The physical adaptations are real: sand-specific strength, tendon conditioning, sun and dry-air exposure, pack familiarity. But almost every athlete who has trained here reports something beyond physiology. Running alone across the hamada at dawn, with 40 kilometers of silence in every direction, recalibrates the relationship between effort and environment. The race stops being an abstraction built from YouTube videos and becomes a place you already know.
That familiarity is worth minutes per stage and, more importantly, it removes fear. Runners who have slept in this desert, eaten in it, watched its weather move, start the Marathon des Sables on home ground.
