THE BIG RACE (3 runners Relay) – 68km

Be careful, for the 2023 edition, the places of relay passage change compared to the previous editions. The passage between the 2nd and the 3rd relay will no longer take place in Mayres Savel but in the Signaraux.

Brief description of the 3 relay races:

  • 1st relay: La Mure – La Mine Image = 15km and 700m of elevation gain
  • 2nd relay: La Mine Image – Les Signaraux = 23km and 1 500m of elevation gain
  • 3rd relay: Les Signaraux – Treffort = 30km and 1 300m of elevation gain

For this 12th edition, the organization offers a course close to the 2022 one, of course keeping the cultural and natural wonders of local heritage, elements that have been very popular in previous editions.

The departure of the race will take part in La Mure, major town of the Matheysin plateau, then you will run on the ascent of Sénépi at dawn, following up with the ski resort of Signaraux. Then you will discover the beauty of La Pierre Percée (Holed rock), one of the 7 wonders of Dauphiné region.  This will then lead you to La Mine Image, an underground museum of La Mine, following up with the ascent of Connex to discover a panoramic view of Monteynard over the historic railway of Petit Train de la Mure. giving you a wonderful view of the lake and the EDF Dam below you, and the Vercors Mountains!

You will follow the ascent to reach the peaks of TPM, l’Alpage du Sénépi, where a sheperd, his family and his team will welcome you! From there, you will run down to Mayres-Savel before crossing the 2 Himalayan footbridges to get from Matheysine to Trièves. You will enjoy beautiful panoramic views over the lake running on the mountainside of Côte Rouge before the final downhill to Treffort beach where the finish line is.

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.
