Défi mars bleu - Marseille

Défi Mars Bleu is a running challenge held in Marseille during March, offering both solo and team participation. It is linked to the effort against colon cancer. The event falls under running and ultra-running categories, emphasizing accumulating distance throughout the month rather than a single, scheduled road race. The solo and team challenges are available for the entire month of March. While specific routes, distances, or start times are not provided, the structure suggests a flexible challenge. Participants can engage individually or as a team, with the colon cancer cause remaining central to the event.
