Cormaris Trail 2027

Cormaris Trail is a trail-running weekend in Cordemais, in Loire-Atlantique, around late January and early February. It is organised by ASC Cormaris Triathlon Athlétisme, the athletics and triathlon section of Cordemais’s town sports association, and it is affiliated with the Fédération Française d’Athlétisme. Runners can choose from several formats: a 30 km long trail, a 20 km relay trail, a 15 km night trail, and a 13 km short trail. The routes use GR long-distance walking paths along the Sillon de Bretagne, the ridge line of the Armorican Massif. The terrain is fairly hilly for the region, with technical passages mixed with faster sections where runners can pick up speed again. Winter weather is part of the challenge, especially for the night race and any muddy or wet trail sections. Salomon, Meltonic, and Endurance Shop Nantes support the event, with Endurance Shop Nantes described by the organisers as a long-time club partner.
