On the occasion of the 2026 edition of MARSEILLE‐CASSIS – AG2R LA MONDIALE, the SCO Sainte‐Marguerite, organizer of the event, is deploying a unique device: Marseille-Cassis Solidaire, an initiative that combines sporting challenge and citizen engagement.
Thanks to this new approach, the race becomes an opportunity to live the experience, to make a concrete commitment differently by giving a social, environmental or inclusive dimension to its participation.
Launched on 4 May, Marseille-Cassis Solidaire offers a new way to join the adventure. Participants can access the race while supporting essential causes for society and the territory, thanks to a collection system that transforms each stride into a useful gesture.
Would you like to participate in the 47th edition of Marseille-Cassis - AG2R LA MONDIALE by supporting one of the selected associations in 2026? Create your solidarity account, choose your association, and start your collection without delay.

By evolving the solidarity mechanisms implemented in previous years, the organizers of MARSEILLE‐CASSIS – AG2R LA MONDIALE wish, with the launch of Marseille‐Cassis Solidaire, to initiate a new dynamic allowing a greater number of associations to benefit from a surge of generosity commensurate with the event.
This initiative draws its inspiration from the Anglo-Saxon models, such as the marathons in London and New York, which have always placed the charity work of runners at the very heart of their competitions. Marseille‐Cassis Solidaire also aims to be a long-term fixture on the local landscape, by supporting a lasting network of associations in Provence that is among the richest and most dynamic in France, and by making racing a real driver of social impact for the territory.
