10 km de Boulogne sur Mer 2026

The 10 km de Boulogne-sur-Mer is a road race held in Boulogne-sur-Mer, a port town on the Côte d'Opale in Pas-de-Calais, northern France. It typically takes place in spring, with the 10 km race offered alongside a shorter 5 km event and, in some event listings, the Semi-Marathon et 10 km de Boulogne-sur-Mer. The course winds through the town and along the seafront, offering participants views of city streets and the English Channel coast, distinct from a closed track or park loop. This event is a long-standing local tradition, enhanced by the town's maritime environment and promoted with the pun “Semi indéBoulognable,” a play on Boulogne's name.
