Odysséa Paris is a 5 km and 10 km charity road race held in Paris, within the Bois de Vincennes, circling the Château de Vincennes. The event combines running and walking, and serves as a fundraiser for breast cancer research. Its non-timed format emphasizes participation over competition. The Paris race typically occurs at the beginning of October Rose, France's breast cancer awareness month. A remote participation option is available via the Odysséa app.
The course takes place in a public park, featuring forest paths and open natural areas within the Bois de Vincennes, distinct from a typical city street circuit. Participants can register individually, with friends or family, or as corporate and association teams, with companies able to field groups of 30 or more. Previous editions highlight the race's charitable mission: participants have supported local breast cancer organizations, including those focused on patient support and care. Past entry fees have been directly allocated to charities combating the disease.
