Entre Terre Et Mer is a nature-running event in Le Relecq-Kerhuon, near Brest, offering 5 km and 10 km races for adults and three races for children. Adult races start in the morning, with the 5 km beginning first and the 10 km following later. The event focuses on short, accessible distances rather than a long trail challenge.
The route combines paths with road sections between Brest and Le Relecq-Kerhuon. Runners go through a wooded valley before reaching open viewpoints over the Brest roadstead and the sea air at the edge of the bay. The KOALA club of Le Relecq-Kerhuon organizes the event, and the children's programme includes a 600 m race for younger participants.
