The 5 & 10 km de Boulogne-sur-Mer is a road race in the city center of Boulogne-sur-Mer, France. Participants can select either a 5 km or a 10 km distance. This is the event's 27th year, and its location in Boulogne-sur-Mer means the course includes sea air, historic streets, and the character of a port city, unlike a course confined to a park.
The 5 km is suited for runners seeking a fast, intense effort, while the 10 km allows more time to find a rhythm and appreciate the surroundings. The event provides timing, aid stations, restrooms, parking, photographers, a cloakroom, and showers. New features for this year include a label, a tombola, and a reward. After completing the race, participants can explore the nearby Old Town and ramparts, the Basilica Notre-Dame, Nausicaá, or take a stroll around the port.
