PTL® Rules


The Petite Trotte à Léon’s itinerary includes technical passages which are much more difficult compared to those of most other trail running races (e.g. the UTMB®). It requires a very good knowledge of the mountain environment.

Some passages may present objective dangers: steep slopes, risk of stone falls, very narrow paths, crossing scree slopes or glaciers, no paths or clearly marked trails...

The route is NOT WAY-MARKED and is often FAR FROM INHABITED ZONES. It is to be completed in total autonomy between life-bases and partner huts.

For their own safety, participants must be able to master navigation with a GPS. They also must be able to read a map, use a compass and an altimeter. They must imperatively race as a team (less than 50m from each other). They must also be able to confront naturally difficult conditions.



UTMB Group organizes the PTL® in collaboration with les Trailers du Mont Blanc association.
It is directed by a Race Committee whose decisions are final.


Participating in UTMB® events implies the explicit and unreserved acceptance of these regulations, the ethics of the event and any instructions sent by the organization to the participants.


  1. Participants in the PTL® must complete the itinerary without going over the time limit. It is not considered as a competitive event and as such does not give official finishing rankings.
  2. It is open to teams of men, women or mixed of 2 or 3 people. The total number of runners will be limited to 300.
  3. Teams are strictly inseparable. In the case of an abandonment of a runner in a team of 3, the 2 remaining runners can only continue after ensuring that their team member has been left at a life-base or refuge and if they have the authorisation of the race HQ. In the case of the abandonment of a runner in a team of 2, both runners have to stop.
  4. The route is to be completed in autonomy, the teams managing their supplies and their rest time as they wish. Along the route, runners may find:
         - life bases (i.e. a main aid stations) open 24/24, where participants may sleep and eat. They will also get their spare bags. Runners have unlimited acces to beds and bunks, but they still must leave the life base before the cut-off time.
         - partner refuges/mountain huts, open 24/24, where competitors may sleep - for free, according to availability - and a eat (in exchange for a meal ticket*. Runners might be able to use beds and bunks only for a limited time, according to availability. 
         - the services offered by any other non-partner hut are at to be paid for by the participants, while respecting the hut's schedule and the peace of its other clients
  5. Assistance is only tolerated at the organization’s life bases. It is strictly forbidden at other points along the route, including partner refuges, when passing through villages or along roads, at the risk of immediate disqualification.
  6. No assistance is allowed along the route (except for the kilometer preceding and following the life bases)

* In the limit of the 4 meal tickets distributed.



To register, each team has to present a file proving each team member's previous experience. Technical experience in the mountain environment, sporting history as well as team motivation will be taken in to account (see Registration page).

A draw may be organized in case of too many pre-registered participants.
If all the teams of 3 selected after the examination of the files do not allow to reach the limit of 300 runners, a draw will be made among the teams of 2.
If the total number of teams of 3 selected after the examination of the files exceeds the limit of 300 runners, a draw will be made among the teams of 3 and no team of 2 will be selected.

The PTL® is open to all people born in or before 2002 (categories espoir to veteran).

To validate their registration, runners must:

  1. Provide a specific medical certificate (*). It must be uploaded to their runner's account before May 31st 2022 (the organization does not accept any medical certificates sent by email or mail).
    If no medical certificate is received by this date, the registration will be cancelled without refund. Warning: as per the FFA regulations, all medical certificates must be provided in French. We strongly advise you to use our official medical certificate template (already including the translation). Any untranslated certificate will be refused.

    Individual accident:
    Each competitor must have their own personal accident insurance policy covering the costs of research and rescue in France, Italy and Switzerland. Such an insurance can be provided by any body of the competitor's choice, and notably from the  Fédération Française d'Athlétisme by the subscription for a licence or even with the  Fédération Française de la Montagne et de l’Escalade or the Fédération Française des Clubs Alpins et de Montagne (with an Air Glacier card for Switzerland).

    For members of the ITRA (International Trail Running Association) it is possible to subscribe to an Assistance – Repatriation insurance which covers the cost of search and rescue world-wide. For more information go to

    By registering for the PTL®, participants commit to respect the environment and the natural areas they cross. In particular:

    • Littering is strictly forbidden (tubes containing gels, paper, organic waste, plastic packaging...).
    • All participants must keep their waste and plastic packaging until they can dispose of it in the trash cans they can find at any aid station or village they pass through. The organization encourages runners to bring a bag to transport their waste.

    To reduce consumption of plastic, both by runners and volunteers, the organization will not distribute disposable crockery (cutlery, beakers, bowls) at any check point or aid station. You are, therefore, invited to bring you own utensils if you wish to eat hot food at the aid stations.


    Every competitor expressly foregoes the right for any images during the event, just as they renounce any right of appeal to the organizers and their partners for the use of their image. Only the organization can transfer this right for images to any media, via an accreditation or relevant license.

    The 2022 PTL® starts from Chamonix and travels through middle and high mountain environments foraround 300 kilometers with about 25 000 meters elevation gain.
    The start is at 08am on, Monday, August 22nd 2022 from the Place du Triangle de l'Amitié of Chamonix ; finishers will be welcomed in place du Triangle de l'Amitié in Chamonix until 16:30, August 28, 2022 and cut-off time for finishing is 152:30 hours.


    Each race-bib is issued individually to each competitor upon the presentation of an ID with photo and after having signed a commitment on their honor to keep the mandatory equipment with them at all times during the race.
     It must be presented at any checks along the race route.
     In Chamonix, the race-bib is “the pass” necessary to access shuttle buses, buses, aid stations, rest areas, showers, and sack drop-off and pick-up points.
    In addition to each race-bib, each team member will receive an ID bracelet, to be worn on the wrist throughout the race.


    A GPS tracker is supplied to each team. This tracker allows the organization to track the progress of the team and ensure that it respects the route. This information will be available on the internet.
    The positioning of the tracker on the bag recommended by the organization must be strictly respected.


    Cut-off times are defined for the life-bases and any other area judged by the organization to be imperative for reasons of security. They are calculated so that participants can make it to the finish line within the maximum permitted time of hours (152:30).  
    In order to be authorized to continue with the event, teams must be able to leave the check point before the cut-off time.
    All participants excluded from the event by the organization and who wish to continue the itinerary do so at their own risk after having returned their race-bib and tracker.


    The organization ensures the repatriation of runners (who abandon or who fail to meet the time barrier) from every check point with a cut-off time.. In the case of abandonment at all other points along the route, without exception, runners must organize their return by their own means.
    The organization will ensure the repatriation to Chamonix of the bags of runners who have withdrawn, on condition that their withdrawal has been registered. The delay of the repatriation depends on logistical constraints and the organization cannot guarantee that all bags are brought to Chamonix before the end of the race. 


    Any complaint must be sent by email, within 10 days after the end of the event.


    If necessary, the organization reserves the right to modify at any time the routes, starting times, cut-off times, the position of aid stations and medical stations, and any other aspect related to the smooth running of the events.
