Cross amu is a February cross-country and walking event held in Marseille, located in the Bouches-du-Rhône department of southern France. The program is concise and functional: a men's 7.5 km cross-country race, a women's 5 km cross-country race, open 5 km and 2.5 km cross-country races, alongside 5 km and 2.5 km walking options.
The morning begins with the men's 7.5 km race. Subsequently, the women's 5 km race takes place, followed by the shorter cross-country and walking events later in the morning. The schedule indicates a local, multi-distance event rather than a singular main race, with participants selecting distances appropriate to their abilities on the same Marseille race day.
