Experience the ultimate island circumnavigation at the Ultra Trail de l'île d'Oléron, taking place on Saturday, April 4, 2026. This epic 100km journey begins at the historic Citadelle of Le Château-d'Oléron at the break of dawn, 5:30 AM, challenging runners to traverse the entire diversity of the island's landscape. The single, continuous loop takes participants through dense maritime forests, sprawling salt marshes, rugged beaches, and iconic oyster-farming villages, utilizing a mix of dirt trails, sandy paths, and scenic coastal cycle tracks. Athletes can tackle the 100km Solo for a personal test of grit, or join forces in Duo or 4-person Relay teams to share the distance. For those seeking a shorter pace, a 12km Walk is also integrated into the event schedule. Registered runners must collect their bibs on Friday, April 3rd, at the Citadelle, with registration officially closing on March 20th. Enhanced race services are available, including GPS tracking beacons for real-time safety and SMS result notifications for immediate celebration. Whether you are aiming to conquer the Atlantic coastline solo or experience the "Luminous Island" as a team, this ultra-marathon offers a raw, atmospheric race through the heart of one of France's most beautiful coastal treasures.
