Trail of the Balconies of the Seine

The Trail des Balcons de la Seine is an annual multi-distance trail event centred on La Roche-Guyon, organised by the Vexin Trail Association and staged from the Cour des Écuries at the Château de La Roche-Guyon. The event (presented on the official event site as Trail des Balcons de la Seine) showcases extensive natural singletrack and viewpoints along the Seine valley within the Parc naturel régional du Vexin français, with most routes run on natural trails. Distances range from shorter community runs to longer ultra-distance courses, and the weekend includes a race village with partner stands and on-site support.

The race weekend is volunteer-led and emphasises a friendly, associative atmosphere with marked courses, refreshment points on longer routes and post-race provisions at the finish. The event page lists multiple distances with their respective elevation gains and scheduled departure times, and entrants are asked to respect course signage and safety instructions issued by the organiser. Practical details such as exact ticket inclusions and contact email are provided on the official registration pages linked from the event site.
