About the Event

Celebrate the arrival of spring by the ocean at the Arcachon Spring Marathon, returning to the stunning Gironde coast on Sunday, March 29, 2026. This isn't just a race; it’s a panoramic journey through the "Ville d'Hiver" with its iconic 19th-century villas and along the sparkling shores of the Arcachon Bay. Whether you are aiming for a sub-4-hour marathon or a scenic 5K sprint, this event combines high-level athletics with the salty, invigorating air of the French Atlantic.

The 2026 edition offers four diverse challenges to suit every stride. The flagship Marathon (42.195 km), the high-performance Semi-Marathon (21.1 km), and a technical 21 km Walk all kick off at 08:30 AM from the historic Théâtre Olympia. For those looking for an explosive short-distance effort, the 5K Run starts shortly after at 09:15 AM. The course is designed to be as visually rewarding as it is physically demanding, leading runners through the most picturesque neighborhoods of this legendary seaside resort.

Logistics are streamlined for the modern runner: the traditional medical certificate has been phased out in favor of the online Health Prevention Path (PPS). The event also relies on a massive community effort, with volunteer positions open for everything from course signaling to finish-line reward distribution. With official partners like Decathlon and Abatilles on board, participants can expect professional-grade support and a festive village atmosphere. Secure your registration today and discover why Arcachon is the ultimate destination for a spring personal best.
