Any enrolment for the Trail 80km of EcoTrail de Paris® 2017 implies the tacit acceptance of the following regulations:


 1.1 EVENT 

A timed running race through the heart of the countryside, following for the most part un unmade-up paths (about 90%). The distance of the Trail de Paris Ile de France is about 80km, for about 1500 metres of ascent. The Start is at the Ile de Loisirs de St Quentin-en-Yvelines (78) and the Finish is located at the Eiffel Tower. The Trail will take place in one single leg, at a free pace, in a limited time, coupled with strict time gates. The Start of the Trail is on Saturday 18th March 2017 at 12h15.



Le Trail is open anyone, man or woman, born in 1996 or before (including hopefuls and veterans categories), graduate or not. 



The principle of individual racing in semi self-sufficiency is the rule for Trail 80km. On the course, there are areas of refreshment provisioned with drinks and food to consume on the spot. Only water (excluding other drinks) is there to fill up flasks and containers.

Each runner must make sure to have, at the start of each refreshment area, the quantity of water and food which are necessary to them to get to the next refreshment point. No personal assistance is authorized on the course outside the refreshment areas set out for this purpose.

Any personal medical or paramedical care is strictly forbidden. It is officially forbidden to be supported along the course by any person other than a regularly enrolled competitor.



Conditions can be very tough in March (night, wind, cold, rain or snow). A very good training and a real capacity for personal autonomy are indispensable for the success of such an individual adventure.

To enrol for the Trail 80km de l'EcoTrail de Paris Ile de France®, you are strongly advised to have already completed a minimum of one 50km trail.

A medical certificate with the mention "Presents no contraindication to competing in running races" dating from no more than a year (so after 18th March 2016) is required to validate enrolment and must be sent to the organisation at the latest on 1st March 2017, with the postmark as proof.

Beyond this date, the enrolment will be cancelled and the enrolment fees lost



Taking part in the Trail 80km of the Eco-Trail de Paris Ile de France® implies a de facto acceptance without reserve of the current regulations and of the ethics of the race published by the organisation, as can be consulted in the section « ethical charter » on the website. 

A little bag specifically for collection the participants' rubbish is handed out to each runner with their race number. The use of this bag is obligatory, and carrying it will be checked out at the control points. Any runner caught throwing down rubbish on the course will be disqualified.

Everyone enrolled undertakes to follow the paths signposted by the organisation, without taking short-cuts. In fact, short-cutting a path causes an irreversible erosion of the site and thus permanent damage. Non-respect for this direction will lead to disqualification.

A large number of dustbins have been placed in each refreshment area and must definitely be used with an approach to a selective sorting of rubbish.

Participants must strictly respect the regulations for visiting the Meudon Observatory and the Saint-Cloud National Estate.

Any person can at any moment of their enrolment take out to a cancellation guarantee, averaging an additional charge of 9 euros per person to add to the costs of enrolment on the same payment. The object of the guarantee is to enable the reimbursement of the costs undertaken for the enrolment in the Trail in the case where a runner requests the cancellation of his enrolment because of one of the following events:

  • an accident or a serious illness leading to going off work for over 3 days,
  • the death of the runner himself,

The demand for reimbursement must reach Les Trailers de Paris, with the above-mentioned proof, at the latest in the 10 days which follow the event. Demands are considered in the two months following the event. No reimbursement will be made outside the annulation guarantee taken out.

Each runner will present proof of identity with photo, will sign an undertaking of honour to keep it with him throughout the race, as well as signing the ethical charter. He will then be handed his race number, accompanied by a bracelet.

The race number must be worn on the chest or the stomach and must be permanently visible throughout the entire race. It must therefore be positioned above any clothing and can in no case be fixed to the rucksack or a leg. The name and logo of the sponsors must neither be modified, nor hidden.

The bracelet must be permanently worn around the wrist for the entire duration of the event. The bracelet is the passnecessary to get to the shuttles, buses, refreshment zones, showers, toilets and zones of deposit and picking-up of bags.



During the issuing of race numbers, an electronic chip is individually handed over to each runner for timekeeping purposes. This must be placed as stipulated in the technical description. Each runner is responsible for the good care of the chip. The runner cannot be timed in the following cases:

  • not carrying the chip,
  • losing the chip,
  • damaging the chip,
  • unorthodox carrying of the chip.



Each competitor brings their own personal effects bag of 20 litres' capacity (change of clothing, toiletries,...). A sticky label supplied with the race bib must be stuck onto this bag.

Having filled it with his chosen belongings and having closed it, he can deposit it, between 09h00 and 12h15 on Saturday 18th March, in the Starting area at the  Leisure Island of St Quentin en Yvelines. No runner's bag will be accepted by the organization on Thursday, March 16 and Friday, March 17.

The organisation then takes the bag to the Finish area in Paris.

Bag recovery in Paris: at the Emile Anthoine sport centre (Finish area). The bags are handed back either to the competitor or to those close to him, uniquely on presentation of the bracelet. Bags will be handed back until 2am on the morning of Sunday 19th March. Beyond this time limit, the runner will have to come and recover his bag, at his own cost, from the organisation at Issy-les-Moulineaux.

Only the bags handed out by the organisation will be taken. As the contents of the bags were not checked, there can be no protest about the contents at the Finish. It is recommended not to put valuable objects in them. 

All the bags must be taken back from the association within 15 days after the event, beyond which date they given to charitable organisations.



On the parts of the course following the public roads, each participant will have to conform with State laws and will alone be responsible for a possible breach of these rules.  

A First Aid station has been set up at each refreshment post. These stations are in telephonic liaison with Race Control. A medical control team is present throughout the entire duration of the event at Race Control.   

The First Aid stations are there to bring aid to any person in danger using the organisation's own or approved means. The official doctors are authorised to take any competitor unsuited to continue the event out of the race (by invalidating his race number). The first-aid workers are authorised to transport those runners whom they consider in danger by any means at their disposal.

In case of need, for reasons always going in the interest of the person being rescued, they can call on the fire brigade, and at that moment, the operations direction will organise all the appropriate means. The costs resulting from the use of these exceptional means will be paid by the person rescued who will also have to ensure his return from the point from which he will have been evacuated. He also can also present a file to his individual personal accident insurance. 

Any runner calling for a doctor or a first-aid worker submits themselves to their authority and undertakes to accept their decisions.



Physiotherapists, osteopaths and chiropodists will be present in Paris at the Emile Anthoine Sports Centre (Finish area) to bring aid to runners after their arrival. Access to the care area is only possible for those runners wearing their bracelet. The first-aid area is open 19h00 on Saturday until 01h30 on Sunday morning. Access to first aid and the nature of the care required are left to the assessment of the first-aid personnel, notably based how busy they are.



"Mobile" control zones of have been set up at several points along the course. Their position is not communicated by the organisation and the means of control will be specified to the participants during the pre-race briefing on Saturday 18th March 2016 at 11h45.

Only runners carrying a visible race number have access to the refreshment areas. The road map will identify a precise list of refreshment points. The refreshment points are supplied with drinks and food to eat on the spot and with still water for refilling your bottle or flask. A post-race mealin the form of a buffet will be served in Paris to all the participants of the Trail who have asked for it during their registration.



The maximum time for the event, for the whole of the course, is fixed at 12h45. The hour limits from the Start (time gates) of the refreshment zones will be defined and communicated in the road map.

These time gates have been calculated to enable the participants to get to the Finish in the maximum time laid down, while still making possible stops (rest, care...) To be authorised to continue the event, competitors must set off again from the refreshment zone before the fixed time limit (whatever their arrival time in the refreshment area).

Any competitor put out of the race and wishing to continue his course can only do so having returned his race number, and must then continue at his own responsibility and in complete autonomy. From then on he can no longer be considered as a Finisher.

In the case of poor weather conditions and/or for safety reasons, the organisation reserves the right to cancel and/or to stop the race underway, even to modify the time gates in liaison with the prefectures concerned.  



It is possible for the participants in the Trail (Finishers or not) to take a shower in Paris at the Emile Anthoine Sports Centre (Paris VII).



Except for injury, a runner must not retire anywhere else but in a refreshment area. He must then tell the area director, who recovers the race number and the chip. The runner keeps their bracelet because this is their pass for getting to the shuttles, buses, meals, and first-aid rooms...

Systematically and obligatorily a runner, having retired, must himself tell Race Control (by phone or by SMS at the special number indicated on the road map). How to get him back will be decided by the post director, based on the following general rules:

  • Buses are available from the Start of the communes indicated on the road map to get those runners having retired back to Paris.
  • Runners who retire at another first-aid post but whose state of health does not necessitate being evacuated, must get back as quickly as possible, and by their own means, to the closest point of repatriation. In case of poor weather conditions justifying the partial or total stopping of the race, the organisation ensures repatriation of the runners stopped as soon as possible.
  • Retiring before a refreshment area and going back, during the meeting with race officials, these will recover the race number and the chip. The runner will then no longer be under the control of the organisation. Using any means, he will then have to tell Race Control of his safe return (by phone or by SMS to the special n° indicated on the road map).



Controllers on the course are authorised to check the obligatory material and, more generally, the respect for all the regulations (runners identity, respect for the site and the ethic, illicit help and accompanying, race number not permanently visible to the front... )

Any runner not in possession, during a control along the course, of the totality of his obligatory material will be immediately disqualified, without any possibility of making an appeal against this sanction.

The displaying or exhibition of brands, sponsors, or partners being strictly forbidden in the area of the Eiffel Tower, the organiser is in charge of respecting this regulation. Because of this, non-respect will lead to an immediate and irrevocable disqualification. In addition, the competitor concerned will no longer be able to enrol in future runnings of the EcoTrail de Paris Ile de France®.

A minimum penalisation of half an hour is applied for any other breach in regulations. The controller tells his post director and/or Race Control and can ask, depending on the seriousness of the act and the behaviour of the runner, for the disqualification of the competitor. The race jury can declare the disqualification of a competitor for any serious breach in the regulations, in particular in the case of:

  • not wearing the race number correctly,
  • not presenting identity papers or the presentation of identity papers not corresponding to those on the race number being worn,
  • not wearing the bracelet,
  • not respecting the State Law on those parts of the course using public roads,
  • not respecting the instructions given by the control post
  • using a means of transport,
  • starting off from a refreshment area after the time limit,
  • not helping another competitor in difficulty,
  • accepting personal assistance outside the official refreshment areas,
  • not respecting the rule not to be accompanied along the course,
  • display or exhibition, in no matter what form, of brands, sponsors, or partners in the Eiffel Tower enclosure,
  • pollution or damage to the sites by the competitor or by a member of his team,
  • insults, rudeness or threats made during a meeting with any member of the organisation or any volunteer,
  • refusal to be examined by an organisation doctor at any moment in the event,
  • drug-taking or refusal to allow a drugs test,
  • not carrying the rubbish bag.



They can be made by letter in the 60 minutes after the posting of the provisional results. 



Any competitor can be given a drugs test during or at the Finish of the Trail. His refusal involves immediate disqualification. Any positive control will lead to his exclusion for life from events organised by the Trailers de Paris Ile de France.



This is made up of:

  • the President of Les Trailers de Paris,
  • the organiser,
  • the race director, 
  • the coordinator responsible for safety,
  • the director of the medical team,
  • the directors of the control areas concerned,
  • as well as anyone considered competant by the President of the Organisation Committee. The jury is authorised to take decisions within a time limit compatible with the rules of the course on all the disputes or disqualifications which occur during the event. The decisions are without appeal.



The organisation reserves the right to modify the course and the locations of the First Aid and refreshment posts, at any moment and without warning. In the case of really bad weather (strong depression with serious amounts of rain and snow, strong risk of a storm...) the Start can be delayed by maximum of two hours, beyond which, the race is cancelled.

In the case of bad weather conditions, and for reasons of safety, the organisation reserves the right to cancel and/or to stop the event underway, even to modify the time gates.

Cancellation, postponement or modification to the race opens no right to enrolment reimbursement.

Any decision will be taken by a jury bringing together at least the race director, the organiser and the coordinator responsible for safety as well as any person competent in the eye of the President of the Organisation Committee.



Personal liability: The organiser has taken out a personal liability for the duration of the event. This personal liability insurance guarantees the financial consequences of its responsibility, of that of its officials and its participants.

Personal accident: Each competitor must be in possession of an individual accident insurance. Such an insurance can be taken out with any organisation chosen by the competitor, and in particular with the Fédération Française d'Athlétisme.



A detailed description of the course will be supplied at the same time as the distribution of the race numbers. It includes practical information such as the hour limits for passing, the refreshment areas, the rescue posts, the care posts, as well as the access points for the accompanying members. A single copy of this book will be given exclusively to those who have enrolled.  



Only those runners crossing the Finish Line will be ranked. No monetary prize will be awarded; all the Finishers will receive the same specific gifts

A general male and female ranking and a ranking for each male and female category will be established: the first 10 men and the first 5 women in the general ranking, as well as the first 3 in each category will receive a trophy or a gift. General classifications and those by category cannot be accumulated. In the hypothesis where less than 10 runners in the same category will be at the Start of the event, then only the 1st in the category will be rewarded.   

The detail of the awards can be given on request at the time of race bib distribution.

By “Finisher” one means all the participants reaching the Finishing Line before the 1-hour time gate of the morning of Sunday 19th March 2017.



In the context of the values of solidarity and for the protection of the environment of the EcoTrail de Paris Ile de France®, it has seemed natural for the organisation to associate itself with a project for the environment and reintegration in partnership with the Office National des Forêts.

From this, it has been decided that the organisation will donate 7500€ into this project thanks to the enrolment of each runner in the 80km Trail.

The choice of the site to be rehabilitated will be agreed by the organise and the Office National des Fôrets and communicated by press release and posting on the event website. www.traildeparis.com



In taking part in the Trail, each competitor expressly authorises the Eco-Trail Organisation (or its assignees) to use and allow to use or to reproduce or allow reproduction of their name, their image, their voice and their sports performance in the context of the Trail with regard to any direct exploitation or in the form derived from the event and this, in any support, in the whole world, through all known and unknown means to-date, and for the entire direction at present granted to these direct or derived exploitations by the legislative or regulatory dispositions, legal or arbitrary decisions of the whole country as well by international agreements, current or future, allowing for possible extensions which might be made to this duration.
