The Semi Marathon d'Airbus Atlantic is a spring road race held in Rochefort, Charente-Maritime, on France’s Atlantic coast. The main event is a half marathon, accompanied by a 10 km race and youth races, offering multiple starts for participants of all ages.
The course is largely flat and accessible, combining urban streets in Rochefort with more open paths, including segments near the Charente river. Participants include Airbus Atlantic employees, residents, and visiting runners. The event also benefits a charitable cause, connecting it to the company, the town, and the local running scene beyond just the competition.
