LE 3e POSTE – 17km


Please be careful, the 2021 edition of the 3e Poste is planned on Tuesday evening, and not on Wednesday, as it has been since its creation!

The registration for the 2021 edition is now open, please be aware that the bibs are limited!



2017 was the 20th anniversary of the closure of the Matheysin plateau mines, for this special date the organization decided to affiliate to this event, offering to the participants a new trial that led you to those paths of this historic and local adventure.

 We therefore maintain this 2017 surprise, offering in 2021 this trial the 3rd Poste in solo and 2 relay runners. The trail leads to the 3 wells of the visible mines and a few marquing spots of this past period : 

  • The departure will take place in Prunières next to the mine well. You will then pass by the high path of La Mure, which has became a very turistic venue in 80’s, right before the closure of the mine!
  • The railway will lead you to Susville well and to the coal store where the ore was stocked before being loaded to wagons, going down the railway between 1888 and 1988. This is where the relay meeting point will take place, for those who share the distance!
  • The trail will follow up on the mountain side of Sénépi and will go along old galeries entries, overlooking at minors villages such as Le Villaret, La Centrale, Peychagnard or Crey.and also « La Centrale Pound » this power station used to run electricity with the coal waste.
  • Finally, the arrival will take place at the 3rd well: the underground musuem of the mine « La Mine Image » in Motte-d’Aveillans

The natural spaces we are working on and the people who are taking care of those lands and territories, which you will be crossing for the race, are factors we do not control 100%. Therefore, we sometimes have to make changes to our different routes, which can slightly modify the distance and/or the altitude difference. This distance and altitude difference is therefore given as an indication.
