Course Des 4 Clochers - Velizy Villacoublay 2027

La Course des 4 Clochers is a 17 km trail race held in Vélizy-Villacoublay, within the Yvelines department of Île-de-France. It takes place in mid-March, coinciding with the start of spring, and is categorized as a nature run rather than a road race. The course follows trails around the Bièvre valley, a designated French natural heritage site. The name refers to four church bell towers, and the event incorporates this theme by suggesting a blend of physical exertion and a pilgrimage-like journey. It functions as a local trail event: brief enough for proficient recreational runners, yet offering sufficient off-road terrain to distinguish it from a simple 17 km flat run.
