Semi marathon la tranche sur mer - La Tranche-sur-Mer 2027

La Tranche-sur-Mer’s race series is a road-running event in Vendée on France’s Atlantic coast, featuring a half marathon and a 7 km race. Scheduled for late April, the main distance is the standard 21.0975 km half marathon. Both races utilize single-loop courses, providing runners with one continuous circuit instead of repeated laps. The route follows the local coastline, with sections along the sea, through marshland, and on roads lined with pine trees. CAP La Tranche organizes the event, and these races mark the association’s launch. The 7 km option is the most popular, making the day accessible to newer runners as well as those targeting the half marathon. Organizers highlight the sea air, summarized by their phrase “an iodized breath with every stride.”
