ATLANTIDE ORGANISATION Internationale reserves the right to modify:

  • • the regulations of the 35th MARATHON DES SABLES,
  • • the aspect of the course (see ART. 21),
  • • the place, the date and destination in case of forces beyond our control: weather, cataclysm, armed conflict, invasion in any form, lock-out…


These will take place on 19 September 2020.

Participants must present themselves to the race administrators and medical team responsible for carrying out these verifications. He or she must imperatively have fulfilled his or her technical, administrative and medical obligations (see ART. 24, 25, 27 & 28) before departure. At the control point, an exact list of each participant's equipment must be established (i.e., compulsory items, personal belongings, food and caloric value, etc.). The race stewards are authorized at any time to check and supervise the participants' backpacks. Individual items of the participant's equipment as referred to in the above list is strictly personal. Any items missing from the list, whether thrown away, lost or stolen, shall be penalized. All competitors are responsible for their own equipment and they must therefore inform the organization of any missing item, failing which penalities could be levied (see ART. 27 and 28). Any found objects that remain unclaimed after 24 hours shall be disposed of, except for telephones, cameras and batteries. Each competitor is responsible for his/her own equipment.
During the race, none of the items in your backpack will be looked after by the organization.


During the administrative and technical registration, the organisation will provide each participant with:

  • 2 breast plates bearing a number, approx. 18 cm x 16 cm
  • one for upper part of the chest
  • one for the back, to be attached to the backpack,
  • a check-in card
  • ChronoTag (3)
  • a distress beacon SPOT

These ID marks must be worn by the participants throughout the race and positioned according to the organization's indications, failing which penalties will be issued. The race stewards may carry out checks at any time. It is formally forbidden to cover the organization's race numbers with any other lettering. Each participant must ensure his/her ID marking is clear, entirely visible, in good condition and in the proper place, under pain of penalty (see ART. 27 and 28). The organization will provide competitors with spare tags in case of damage or loss. The distress beacon must be handed in at the end of the race. The loss of the distress beacon will incur a fine of 100 euro (see ART. 27 and 28).

Each participant agrees to adhere strictly to this rule, subject to serious penalty in the case of violation (see ART. 27 and 28).


In addition to official ID markings, participants may use other available clothing space for individual sponsors e.g. T-shirts (apart from the chest area exclusively reserved for race number) shorts, socks, caps, backpacks, etc. However, the organization reserves the right to prohibit sponsorship considered to be oversized or in direct competition with the organization's partners or for any other reasons and which the organization does not have to justify.

The upper part of the chest area is reserved exclusively by the organisation for positioning your race number. The race organizers will be very strict about where your ID is placed. Therefore, think carefully about where to position your advertising and publicity on your tee-shirts and backpacks.


Stage starts are grouped, except for:

• the "non-stop" stage, where the leaders of the general and women's classifications will start around 3 hours after the 1st start.

• the "marathon" stage, where the last on the list will be the first to leave.

Each competitor must attend a briefing session with the race Director before the stage starts.

Participants must imperatively start at the time indicated by the organization, subject to penalties (see ART. 28).

The water distribution point at the finish line of each day's stage is compulsory check point.

Check points are located throughout the course of each stage of the race. There are two to six check points depending on the length of the race and each competitor must go through them, if not penalties will be applied (see Art 27 and 28). This allows the race officials to record times and distribute water (see ART.16).

Medical assistance will be available at each check-point.

The closing times for each checkpoint will be indicated in the road book.


An official time-keeper will take down the daily order of arrival for each competitor.

Obligatory checkpoints: water distribution and card punching.

The bivouacs will be pitched each day on previously chosen sites transformed into camping grounds for the competitors; Numbered, 8-man tents attributed by country of residence. Failure to adhere to these numbers will incur a penalty (see Art. 27 and 28) Competitors may use their free time to prepare for the night and get medical care, if necessary.


Each competitor's time is recorded in hours, minutes and seconds.


The daily race ranking is calculated by adding the time taken to run that stage of the race plus penalties, if applicable.


Each team's time will correspond to the average time taken by its members, including penalties.


General ranking is calculated by adding together times for each stage of the race. Any claims must be made in writing at the race and handed over to the ranking marshals (see Art. 27).


The organization takes charge of supplying water to each competitor.

Water is typically distributed as follows.

Liaison stage:

Penalties will be given to competitors who abandon empty water containers along the route. Facilities for handing in empty containers will be available at check points (see ART. 27 and 28).

Never leave without water. Should you get lost in the desert, water reserves could be vital.


A specially chosen medical team, specializing in sports and tropical medicine will be present throughout the race with the use of assistance vehicles. It will be posted at check points and at the finish line each day and will ensure that any participants who are suffering from physical or mental exhaustion are brought back to the base camp. The medical team is allowed to remove ID plates and to eliminate any participant they feel physically unfit to continue the race and/or having received vital medical care. (See ART.27 and 28).


In no circumstances (and at the risk of having to pay the search costs involved) must any competitor leave the race without informing the organization and signing an official discharge provided by AOI. If a competitor abandons the race, he/she must notify the organiszation as soon as possible and give his/her identification marks to one of the course stewards.

A team which has more than 3 members and where one member drops out or is disqualified will result in the team receiving a one-hour penalty (see Articles 27 and 28).

In the case of a serious physical condition, repatriation may be arranged immediately.

If the competitor's physical condition is satisfactory, he or she shall be taken to Ouarzazate within 48 hours maximum, after signing an official disclaimer supplied by AOI. While awaiting transferral to Ouarzazate, the competitor shall automatically be taken care of and must hand over his or her food to the organization.

The organisation reminds all participants that the 35th MARATHON DES SABLES is a race through the Sahara where climatic and ground conditions can be extreme. Any outside assistance is strictly prohibited. Replenishment during the race shall incur a minimum penalty of 3 hours and possibly exclusion. If a competitor goes far off the race route, necessitating a lengthy search, he or she will be excluded from the race and pay a € 200 fine (see ART. 27 and 28).


An insurance policy covering medical evacuation is arranged by the organization for all entrants.

The policy covers the following:

  • evacuation on medical grounds and corpse repatriation in the event of death: real costs for all competitors to return to Morocco, mainland France, European Union member countries and Switzerland.

        QUARTZ Event program

        The Organization of the MARATHON DES SABLES has decided to set up the QUARTZ Event Program to protect participant’s health and to contribute to doping-free sport.

        The QUARTZ Event Program has neither the vocation nor the competence to replace anti-doping rules but aims to strengthen the medical supervision before, during and after the competition.

        The QUARTZ Event program is carried out in collaboration with the International Trail Running Association (ITRA), Athletes For Transparency association (AFT) and Ultra Sports Science Foundation (USS).

        The QUARTZ Event program is managed by a Medical Commission solely composed of doctors. This Medical Commission can take advice from experts of its choice and specifically give a consultative advice to the race direction on the medical condition of participants.

        This Medical Commission can go as far as to suggest to the race direction that a participant should be excluded from competition for health reasons before competition (« no start ») or not ranked after the competition for non-compliance with the procedures.

        The QUARTZ Event Program is for each participant who agrees to:

        1. Declare to the Medical Commission the following medical information:

        • Any medical history and/or pathology, in particular those which may increase risks during competition.
        • The use of regular treatments or medication or dietary supplements at least during the 30 days prior to the start of the competition.
        • Request or use of a substance or method subject to a Therapeutic Use Exemption (TUE).

        The declaration of medical information to the Medical Commission is done through the ITRA health space for which each participant has access after having created a free runner account on the ITRA website:

        The declared medical information is only accessible by the doctors of the Medical Commission, the designated experts as well as to the medical team during an eventual care during the competition.

        2. Provide all urinary and/or blood and/or hair and/or salivary samples required from 30 days before the competition and up to 15 days after the competition and also consent to the associated analysis of these samples, on the understanding that the costs for sampling and analyses are covered directly by the Organization.

        3. Do not participate in the competition when using:

        Within 60 days before the start of the competition and during the competition
        -    Intravenous iron infusion

        Within 7 days before the start of the competition and during competition
        -    Intravenous infusion

        -    Gas inhalation

        -    Substance subject to a Therapeutic Use Exemption (TUE) according to the WADA (World Anti-Doping Agency) Prohibited List published annually

        -    Glucocorticoids regardless of the mode of administration

        -    Thyroid synthesis hormones except in case of partial or total removal of the thyroid or hypothyroidism of medical origin.

        Within 24 hours before the start of the competition and during competition
        -    Beta-2-agonist regardless of the mode of administration

        -    Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) regardless of the mode of administration

        The possible use of these different substances may be identified in the context of the analysis carried out before and/or after the competition or any other means of investigation.

        4. Accept to answer any meeting request on site or remotely (phone or videoconference) that the Medical Commission may ask for in order to discuss their ability or not to participate in the competition or not to be rank after the competition.

        5. Submit any doping control form legible completed within 30 days before the start of the competition and up to 15 days after the competition.

        6. Accept the use, for the only purpose of research and in a strictly anonymous way, of data concerning him. Each participant has a right of access, rectification and opposition to data concerning him. The Medical Commission is the authority with which the participant can exercise this right.

        Any unreasonable breach, refusal, or transmission of erroneous information in connection with the QUARTZ Event Program can result in the exclusion of the participant from the competition before the competition or not to be rank after the competition.
