La Solidaire de Brest begins and ends at Port du Moulin Blanc in Brest, a major port city in Finistère on France's Brittany coast. This road-running event offers a 5 km, 10 km, and half marathon, alongside a 5 km walk suitable for children and adults. The race typically takes place in late March or early spring, having been held annually since 2017. Its name reflects its purpose: the event supports charitable causes, with various associations benefiting each year.
All courses are single loops, with the half marathon measuring the standard 21.0975 km. Participants will pass Océanopolis near the start and then run along beaches and through the port, with numerous boats visible. The longer races incorporate natural and forest trails, ensuring the course extends beyond city streets and waterfront areas. Handisport categories are featured, team participation is possible for all distances, and individuals unable to attend in person can join virtually via STRAVA.
