La Chambérienne is a night urban trail race held in Chambéry, located in the Savoie department of France’s Auvergne-Rhône-Alpes region. It takes place in November and features two city-trail distances: 10 km and 21 km, each designed as a single-loop course.
The 21 km race is the primary event, available for solo runners or two-person duos. The 10 km offers a shorter solo option, maintaining the same nighttime, in-town format. The event emphasizes its Chambéry roots with the slogan “Trop Chambé !”, positioning itself on the regional running calendar as a concise city race distinct from extended mountain runs.
