On the Pont d'Iéna, in the 16th arrondissement, very close to the Trocadéro.

The start of the 20 km of Paris is on the Pont d'Iéna, above the Seine, in the 16th arrondissement near the Trocadéro. From there, this road race takes you toward western Paris and the Bois de Boulogne, then the 20 km of Paris comes back along the riverbanks before you reach the finish at the foot of the Eiffel Tower! 🏁
