The French Ministry of Ecology and Transport has authorised closure of the motorway for 4 hours.
Traffic is therefore stopped between 8am and 12pm. With support from the DIR Massif Central, vehicles are diverted to allow runners to cross the 5.2 km of the Viaduct, which is cleaned afterwards. The Compagnie Eiffage du Viaduc de Millau mobilises its teams to ensure that the Viaduct can be closed and reopened within the allotted time. After safety checks, the motorway is once again opened up to vehicles.
The overriding feeling that one feels taking part in a race such as this one is a feeling of originality, a sense of freedom – it is as if you are floating in the wind above a sea of greenery. These are the values promoted by a sport that is constantly growing. The latest studies clearly show that French people are interested in running. It is a sport that is open to everyone, male and female, with people of all ages taking part.
The event is a major logistical exercise organised down to the very last detail thanks to local associations, in particular, who help out with refreshments, at security points and with giving out race numbers. In this way, even those who do not run can enjoy the event from the inside! This means that a lot of people − almost a thousand volunteers − can get involved.
