The Airbus Atlantic Semi-marathon is a spring road race held in Rochefort, a coastal town in western France with a significant naval history. Taking place each April, it offers participants two distance options: a half marathon covering the full 21.1 km, and a 10 km race for a shorter challenge.
The location is a key feature of the event. Rochefort is situated near the Atlantic coast, providing runners with coastal air, passage through historic streets, and a sense of a town defined by its maritime heritage. The race is supported by corporate sponsors and is well-organized, drawing most of its participants from local and regional running groups rather than a large international field.
