Accompanying persons, live the race with your runners!
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 which you will find by clicking here.

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 will allow you to reach all the villages crossed by your runners without any trouble.

(as from Wednesday morning)

1 ou 2 people : 30€ per person
3 people or more : 27€ per person

Groups of 3 people or more therefore benefit from a 10% reduction per bus pass.
