Cours'Son Nature is a trail race held in Courçon d'Aunis, located in the Charente-Maritime department of Nouvelle-Aquitaine, France. Typically scheduled for March, it offers participants two off-road courses: a 10.5 to 11 km route and a 22 km option.
The race takes place in the natural and forest environment surrounding Courçon, eschewing a city-road format. Its ethos is deeply rooted in environmental stewardship, being designated as zero-waste and eco-responsible. It is affiliated with the Trail Runner Foundation and utilizes the event to promote trail maintenance and community awareness. The motto, “T’as cours’son prétexte pour transpirer !”, humorously suggests having a reason to exert oneself.
