The Marseille-Cassis Classique Internationale is an annual half marathon which follows a course from Marseille to Cassis in France during the last weekend in October.

It has the silver label of the IAAF Road Race Label Events and is thus among the ten more prestigious half marathon races in the world.

First organised by the SCO Sainte-Marguerite sports club in 1979, the event has grown into a large international competition, with around 20,000 runners competing every year.

[2] Still, the race is made more difficult by a long 327 m rise up a hill—the Col de la Gineste—at the midpoint of the course, which eventually follows back down into the port of Cassis.

[4] There are also two other races which complement the main competition: first organised in 1990, the "L'Autre Marseille-Cassis" (The Other Marseille-Cassis in English) is a mountain hike which negotiates the Massif des Calanques area.
