About the Event

Celebrate a landmark running tradition in the heart of a unique natural park at the 30th edition of the Semi-Marathon de Brière on the weekend of 28-29 March 2026. This beloved event, set against the stunning backdrop of the Parc Naturel Régional de Brière with its ancient marshlands and canals, offers a complete sporting weekend for the entire community. The festival kicks off on Saturday with children's races ("Les Galopades") and Nordic walking, building towards Sunday's main events: a classic 21.1km semi-marathon, a two-person relay option, and a 5km race. Renowned for its warm, convivial atmosphere and exceptional organization by the ESCO club, this anniversary edition promises a flat and fast course ideal for both seasoned runners and enthusiastic newcomers. As a true community pillar, the event also welcomes 200 volunteers to help create an unforgettable experience. Mark your calendar for late January 2026 to secure your bib in this milestone celebration of sport, nature, and local spirit.
