6D LACS-Pictot

6000D edition 2025, 35 years of pleasure… July 31 to 2 august

The 6000D, a legendary race and the first of its kind, is still considered a challenge by most trail runners.

Individual challenge, accessible to all

Starting and finishing in Plagne Bellecôte, this 30km trail race has 1500 m of elevation gain and is less demanding than the 6000D but with an equally beautiful and remarkable course.
This route, which follows that of the 6000D, will branch off at Dérochoir to go towards Plan Bois and go back up to Arpette to join the 6000D route and then descend to Plagne Bellecôte.

The atmosphere 6D Lacs
