The registration for the Mont-Saint-Michel Marathon in the Manche department will begin on Tuesday, October 13, 2026. The marathon is set to take place on Saturday, March 20 and Sunday, March 21, 2027. The event will include both a full marathon and a half marathon, offering participants a chance to run through the scenic and historic surroundings of the Mont-Saint-Michel area, a UNESCO World Heritage site. Jérémy Larson, the outdoor director at Playground, the company organizing the marathon, shared details with Ouest-France in the days before the registration launch. He emphasized the unique challenges and rewards of running in the region, which is known for its dramatic coastal landscapes and tidal changes. The course will include parts of the Mont-Saint-Michel’s famous tidal flats, which are exposed during low tide, adding an unusual element to the race. Participants will have the option to choose between the full marathon, which covers 42.195 kilometers, and the half marathon, which spans 21.0975 kilometers. Both races will start and finish in the town of Saint-Malo, a historic port city in Brittany. The event is expected to attract both local and international runners, drawn by the combination of natural beauty and the challenge of running in a unique environment. The marathon aims to promote the region’s natural and cultural heritage while also supporting local charities. Registration details, including entry fees and deadlines, will be available on the official website once the registration campaign officially begins on October 13. Runners are encouraged to prepare for the event, which is expected to be both physically demanding and visually stunning.
