Whole courseGeometryThrough the Bois de Boulogne, then the Seine quaysAbout 4 km in the Bois, then the quays to the Pont Royal.
The organiser calls the course fast and rolling, with few restarts and changes of direction. After the Bois, through the Porte Molitor and boulevard Murat to the Porte de Saint-Cloud, the way to the quays is more direct, with fewer bends and a short descent. The start was on the Pont d’Iéna and the finish by the Eiffel Tower, on 11 October 2026.
