Before and during the races on July 23rd in the morning through to early afternoon, vehicle traffic will be severely disrupted when approaching the circuit. In addition, parking will be difficult or impossible in some areas, particularly near starting sites (Perros-Guirec and Landrellec) and the finish line in Trebeurden.
The organization recommends that you check the traffic directives published on the public websites of the cities crossed by the race (Trébeurden, Pleumeur, Trégastel, Perros).
Below is a provisional schematic view of the recommended routes for access to towns and villages concerned (highlighted routes on the map), and details of traffic restrictions *.
In any case, have a look on the shuttle service at your disposal.
