The Cross Triathlon du Stade Français is an April off-road triathlon held at La Faisanderie, within the Domaine National de Saint-Cloud in Hauts-de-Seine, west of Paris. Stade Français Omnisports organizes this event, which follows the standard three-discipline structure: swimming, mountain biking, and running.
The park's environment distinguishes it from a road triathlon. The courses wind through tree-lined paths and open fields. The competition includes participants from the youngest "poussin" categories up to adults, making the day suitable as both a club competition and a family gathering. Many participants focus on personal challenge rather than achieving top-tier rankings.
