Marseille en Rose is a charity road race and walk held in early October at the Parc de la Maison Blanche in Marseille, located in the Bouches-du-Rhône department of southern France. This event is organized by a Marseille-based loi 1901 non-profit association as part of the Octobre Rose initiative, focused on raising awareness and funds for breast cancer research. All proceeds are donated to the Institut Paoli-Calmettes, a significant regional cancer treatment and research facility.
The event offers a straightforward and adaptable format: participants select loops within the park, covering distances of 2 km, 4 km, 6 km, 8 km, or 10 km, with the option to either run or walk. Separate starts are provided for children and adults, allowing families, colleagues, friends, novice participants, and experienced runners to unite for a common cause without the constraint of matching speeds. A past edition attracted close to 1,600 participants, demonstrating the local appeal of this smaller-scale event centered on breast cancer prevention and medical research.
