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.

An ambitious and eco-responsible transport plan

At a time when eco-responsibility is at the heart of our concerns, sport too must set an example. A first public transport plan was set up in 2004 (for the second edition of the UTMB®) in order to drastically reduce car use and the resulting polluting emissions. In 2017, the entire organisation was renewed to encourage runners and their entourage to take the bus and to prevent the use of near-empty vehicles. In 2018, the organisation created a new transport plan called UTMB®BUS, to follow runners throughout their race. During the event, UTMB® and its partners set up an exceptional public transport network for runners, their entourage and spectators with two objectives: to enable them to enjoy the races in the best possible conditions and to limit the impact on the environment, particularly the emission of greenhouse gases. The UTMB® is an environmentally friendly event.

During the race

  • The organisation of a transport plan for the runners and the supporters allowing movement around all the strategic points of the race route.
