Set against the stunning backdrop of Hossegor's Lac d'Hossegor, nestled between the Atlantic Ocean and the Côte d'Argent, the Infinity Trail is an exhilarating endurance challenge that pushes runners to their limits. The race follows a unique format inspired by the Backyard Ultra concept, featuring a 6.7-kilometer loop around the serene lake. Each lap must be completed within one hour before starting anew. This cycle continues relentlessly until only one runner remains on the course. As such, the event can last anywhere from ten hours to over a hundred hours, depending entirely on participants' stamina and determination. Whether your goal is to complete a marathon distance or push even further into ultra-marathon territory, you set your own boundaries in this race. The loop itself offers a scenic journey around Lac d'Hossegor through wide, nearly flat paths that hug the water's edge. The ever-changing landscape due to tidal shifts transforms the atmosphere of each lap despite following the same route, providing runners with a dynamic and engaging experience. Spring weather in Hossegor is typically mild and pleasant, ensuring comfortable conditions for both participants and spectators. The race begins and ends at the iconic Jaï-Alaï grand hall, where ample space allows for optimal comfort during downtime between laps. This historic venue also serves as an ideal gathering spot for runners and their supporters to enjoy a convivial atmosphere throughout the event. With its picturesque setting and unique format, this Infinity Trail promises not only physical challenges but also unforgettable moments in one of France's most scenic locations. The race is designed to cater to all levels of endurance athletes, from those looking to test themselves over marathon distances to ultra-runners aiming for personal bests. The ever-evolving scenery around the lake and the supportive environment at Jaï-Alaï make this event a must-attend for anyone seeking an extraordinary running experience in one of France's most picturesque settings.
