Marathon des étoiles de la baie - Plomeur

The Marathon des étoiles de la baie is a 42.195 km road marathon held in Plomeur, Finistère, on the Breton coast of France. Scheduled for late August, it guides runners through the heart of Bigouden country, with the sea nearby. The race's identity is linked to the "stars" in its name. The course follows a seaside route through a protected natural setting. Its primary appeal is the full marathon featuring coastal views, rather than a city-street tour. The event also supports a cause: it is run as a solidarity race against pediatric cancers, providing a community purpose beyond the finish.
