Ninety-nine patients will walk through Paris between October 3 and October 4. The first registered participants were selected, provided that "their health condition allows them to walk," explains Dr. Patrice Delga, a gynecologist-obstetrician surgeon who supports the Casiopeea association. "I am retired, but I intervene and I bring my expertise and full support," he adds. The event is part of Pink October, a global awareness campaign for breast cancer, and marks the fourth edition of the Pink Marathon, a 42-kilometer nighttime walk during the night of October 3 to 4. The Pink Marathon is organized by the Casiopeea association, a French non-profit focused on breast cancer research and patient support. The event takes place at night, a unique feature that adds both challenge and visibility to the cause. Participants, who are patients and survivors of breast cancer, walk through the streets of Paris to raise awareness and funds for the association’s initiatives. The route of the Pink Marathon includes several landmarks in Paris, allowing participants to experience the city while raising awareness about breast cancer. The event is not only a physical challenge but also a symbolic act of solidarity among those affected by the disease. It aims to highlight the importance of early detection and the need for continued research and support for patients. Dr. Delga, who has been involved with the event since its inception, emphasizes the importance of community and support in the fight against breast cancer. "This marathon is more than a race; it's a movement that brings people together for a common cause," he says. The Pink Marathon continues to grow in popularity, drawing both local and international attention to the cause.
