The Corrida du Marais-Vernier is a spring race meeting held in Marais-Vernier, Eure, Normandy, France. It provides road running and walking options: a certified 10 km, an FFA-certified half marathon, a power-walking route of approximately 7 km to 7.5 km, and a hiking option for those preferring a slower pace through the marsh. The organizing association, established in 1997 with the half marathon as its primary objective, has since expanded its offerings as the event grew. It now hosts four annual events, attracting close to 1,000 participants.
The courses feature single-loop routes within the Marais-Vernier, with organizers noting no significant difficulty. The half marathon is 21.1 km, and the 10 km is also certified. The route winds past Norman thatched houses and apple trees in bloom, lending the race a distinctly local Norman character rather than a generic road-course feel. Participants can select walking or shorter distances, while experienced runners may opt for the 10 km or half marathon. Volunteers are essential to the event's continued operation each year.
