The Trail 18km has become a race to foot timed nature, borrowing largely unpaved trails, a distance of 18km, for around 400 meters of elevation gain. The place of departure is on the Observatoire de  Meudon's Terrace (92) and place of arrival in the Domaine National de Saint-Cloud (92).

To meet the timing, the Trail 18km will take place in one step, to free pace, in a limited time, coupled with strict time gates.

The departure of the Trail 18km will be given Saturday, March 18, 2017 from 8:30 to 9:00 in waves.

In previous years, the 18km was not a race as such but more a discovery of the race in the wild.


In pairs:

All you have to do is to make up a pair with the person of your choice, all combinations being possible (wife, husband, child, friend, colleague...unknown (male or female) to meet up at the Mail Branly in a spirit of conviviality and sharing.

Each participant, at the time of their enrolment, need to specify the person with whom they would like to run (Note, this person must also be enrolled!) and for all those who might not have a pair, the organization will be able to find you one if you make the request for a partner on the same level among the others enrolled participants.

Sustainable development:

Because for Trailers, the respect for Nature, a playing field as magnificent as it is fragile, is a fundamental principle, the Eco-Trail de Paris IDF® undertakes to promote the use of public transport.

Finally, there is nothing more natural for the Eco-Trail de Paris IDF®, than to support the associations which share the same values of solidarity. It has therefore been decided that on the enrolment of each pair, the organization will be paying 2 € to the Foundation of the Apprentis d'Auteuil which educates and trains more than 13 000 young people in trouble to allow them to fit into the society.
