Urban Trail de Rosny-sous-Bois 2026

The Urban Trail de Rosny-sous-Bois is an 11 km city trail in Rosny-sous-Bois, Seine-Saint-Denis, east of Paris. It takes place around mid-June, turning the town's streets and corners into a short urban challenge instead of a countryside trail. The course aims to showcase Rosny-sous-Bois from a different perspective, linking running performance with exploring the city on foot. The Running Collective organizes it, using the slogan “Your urban playground!” Elevation gain, start time, and price are not detailed.
