6000D edition 2021, 31 years of pleasure… July 22 to 24

The 6000D, a legendary race and the first of its kind, is still considered a challenge by most trail runners. For this 31st edition the organizing committee offers you
NEW FOR 2021 with the 6D Marathon.

Individual challenge, accessible to all

You’ve run a Marathon on flat, hard, roads, now is your chance to come and discover a different kind of Marathon – on mountain trails and paths. On the program, 42km and a positive elevation of 2000m. A route that takes runners from the village of Aime la Plagne to the valley, to Lac des Blanchets at an altitude of 2363m with a passage through the high-altitude resorts of La Grande Plagne to then descend through the forest to Montchavin les Côches for finish along the Isère river. This new course will bring up to date the original route of the 6000D with the 1st climb following the initial route first run in 1990. A marked course of high quality, 95% on paths and trails.

The atmosphere 6000D

There will be a large, enthusiastic crowd all along the trail to cheer you on you during the 31th edition, on Saturday, July 24th 2021. 

In order to be as close as possible to the Trail spirit, there is only 3 refreshment point (food and drinks) and 1 water point (drinks only) over the 42 km. A camel bag or a gourd holder is strongly recommended.
Running in self-sufficiency is recommended.
