The PTL®

The PTL® (Petite Trotte à Léon) is one of the events on offer within the framework of the UTMB®.
Its conception is original and its unusual specificities distinguish it from other races. The spirit of the  PTL® depends upon mental engagement, an adventurous team spirit as well as sporting values and also those of the mountains.

This ultra-endurance pedestrian event leads participants on a large tour of Mont-Blanc (300km and 25000m of ascent), taking high routes, without way-markers on the ground, which necessitates the sense of orientation on and off paths. Each year the route is different to allow for the discovery of the richness and diversity of paths in France, Italy and Switzerland within the Mont-Blanc massif.
The  PTL® is realised in teams of 2 or 3 inseparable and loyally supportive people, without final ranking. The teams move through a rough, technically exacting and mentally and physically  demanding mountain environment.


With regard to the difficulties inherent to this event, applications are selected from a file of experiences submitted by each established team (see paragraph 2018 Registration).

For its 11th year the start of the PTL® is fixed for Monday August 27th 2018 at 9am, from the Place du Triangle de l'Amitié in Chamonix. The finishers will be judged in the same place, until Sunday September 2nd at 16:30, so a maximum time of 151:30 hours.

The proposed course around Mont-Blanc, omnipresent, and its prestigious satellites, is this year still innovative and outstanding. You will cross little known areas, often difficult to access and with the most breath-taking views.

2018 PTL® regulations


The itinerary taken by the  Petite Trotte à Léon includes technical passages very much more difficult than those encountered in most other trail races (notably 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, the crossing of stone fields or névés, absence at intervals of paths or clearly marked track...

The route is NOT WAY-MARKED and is often FAR FROM INHABITED ZONES. It is to be realised incomplete autonomy between life-bases and partner refuges.

So as to progress in security competitors must be able to master navigation with a GPS and also have sufficient knowledge in map reading, the use of a compass and of an altimeter. They must also be able to confront naturally difficult conditions.



The PTL® is an event co-organised by the Sarl Autour du Mont-Blanc and les Trailers du Mont Blanc (association law 1901 officially registered  on 29/11/ 2003 under n° 1627, Club FFA n° 074060) within the framework of the UTMB®.

The 2018 PTL®  starts from Chamonix in the form of a circuit in the middle and high mountain of around 300 kilometres with about 25 000 metres of ascent.
The start is fixed for 09:00, Monday, August 27th 2018 from the place du Triangle de l’Amitié, Chamonix; the finishers will be registered in the same place until 16:30, Sunday, September 2nd 2018, which gives a permitted maximum time of 151:30 hours to complete the route.


Each race-bib is issued individually to each competitor upon the presentation of photographic identity, after having signed a commitment on their honour to keep the obligatory equipment with them at all times throughout the race.
 It must be presented at any checks organised a long the race route.
 In Chamonix, the race-bib is “the pass” necessary to access shuttle buses, buses, refreshment posts, 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.


Time barriers are defined for the life-bases and any other area judged by the organisation to be imperative for reasons of security. They are calculated so that participants can arrive at the finish within the maximum permitted time of hours (151:30).  
In order to be authorised to continue with the event, teams must be able to leave the check point before the time indicated.
All contestants excluded from the event by the organisation and who wish to continue the course do so at their own risk after having returned their race-bib and tracker.


The organisation assures the repatriation of runners (who abandon or who to fail to meet the time barrier) from life-bases, without commitment of a timeframe.
In the case of abandonment at all other points along the route, without exception, runners must organise their return by their own means.
In the case of abandonment, the return the spares' sack to Chamonix can not be guaranteed before the end of the event.
