The ESSEC Night Run begins after dark on the ESSEC campus in Cergy, offering participants a choice between 9 km or 16 km. Organized by Raid ESSEC, this night race requires all runners to use a headlamp. The 16 km race commences first in the evening, with the 9 km race starting half an hour later. The event's design centers on running the campus and Cergy area under illumination, diverging from a typical daytime road-race format.
The course incorporates the Axe Majeur, Cergy’s significant landmark featuring steps, terraces, and open vistas, grounding the race in the city's identity. The event welcomes participants of all skill levels, featuring entertainment at the start-finish village, activities along the route, partner prizes for all competitors, and additional awards for the quickest runners.
