UTMB® an eco-responsible event

Let's respect this great playground

Ultra-Trail® : l’environnement est une priorité! par UltraTrailMontBlanc


The Mont-Blanc Massif is actually a fragile natural environment to which we must pay great attention. To contribute to the protection of it, we are counting on the engagement of each person. We have the duty of doing all that we can to limit our impact to the minimum.

As the organiser, the UTMB® has developed numerous actions to protect the natural environment and to raise awareness amongst all the players. This is a collective action which involves the organisation, regional groups, runners and supporters, partners and volunteers( Ambassadors for the Environment).

We, ourselves, have formed a Commission for the Environment which guides the projects and we set ourselves ambitious environmental objectives. We are always looking for ways of progressing in this domain and incite everybody to adopt an ecologically responsible attitude.

Contribute to the boreal lynx restoration plan

From the north of the Jura to Alpe d'Huez, the boreal lynx hides in our mountain forests. Very vulnerable, this majestic cat is in danger of extinction in France. The Mont-Blanc massif is a key area for strengthening its population and extending its range in the Alps. A concerted action plan must be drawn up and the funds collected from the UTMB will partly finance the work of drafting this national plan for the restoration of lynx populations.
