Triathlon Avenir Courbevoie is a youth triathlon held near the end of March in Courbevoie, west of Paris. It is organized by the local club and the City of Courbevoie, targeting young athletes aged 6 to 19, with nearly 400 participants per edition. The race is sanctioned by the FFTRI and is a designated event in the Challenge Avenir Ile de France series.
The event takes place within the city. The swim is in a 50-metre Olympic pool. The bike course is on a secured route closed to traffic, and the run is entirely pedestrian, simplifying management for younger age groups. For the Minime, Cadet, and Junior categories, organizers include a short climb to provide a more challenging course for older competitors.
