UTMB®BUS for supporters

We aim to offer you an event which respects the environment: your role is as important as that of the runners! Together we can participate in the preservation of the natural areas which make our landscape beautiful by applying several simple rules.

One of our actions which is effective is the use of communal transport: let us, together, avoid this race in the middle of nowhere becoming an "motor festival", and use the organisation’s buses!

An exceptional public transport organisation will allow you to reach all the villages crossed by your runners without any trouble.
