The Ekiden France Environnement is a road relay marathon held at Stadium Lille Métropole in Villeneuve-d'Ascq, near Lille in Hauts-de-France, scheduled for mid-October. Six-person teams complete the full 42.195 km marathon distance. The legs are set: 5 km, 10 km, 5 km, 10 km, 5 km, and 7.195 km. Each runner must be distinct, making it a team effort rather than relying on one strong individual.
The course utilizes a loop, run once or twice based on the relay leg. This format originates from Japan, where an ekiden is a long-distance team relay. This version emphasizes handoffs, pacing, and team support. The shorter legs suit club runners, students, workplace teams, families, beginners, and experienced runners aiming to test their speed over 5 to 10 km. Children's and junior races are also included, extending the day beyond the main six-runner marathon relay.
