About the Event

Immerse yourself in a true trail running festival in the heart of the French Alps at the 14th edition of the Raidlight Trail Festival from May 15-17, 2026. Based in the stunning mountain village of Saint Pierre de Chartreuse, this three-day celebration offers a spectacular range of challenges set within the protected landscapes of the Chartreuse Regional Natural Park, a Natura 2000 site. The main day, Saturday the 16th, features four iconic distances: the demanding 46km Maratour, the classic 33km Trail Tour, the accessible 24km Semi Trail, and the scenic 17km Festi'Trail, catering to everyone from elite runners to enthusiastic hikers. The festival kicks off on Friday with a thrilling Kilometer Vertical race—a pure 900-meter ascent over just 4km—and concludes on Sunday with the technical 27km Sky Trail, ensuring a non-stop weekend of alpine adventure. With a strong ethos of environmental respect for the fragile mountain ecosystem and a cap of 1,800 total participants, the event maintains an intimate, community-focused atmosphere praised for its exceptional organization and incredibly friendly volunteers. It's the perfect destination for trail runners seeking authentic, challenging mountain races combined with the festive spirit and breathtaking scenery of the French Prealps. Lace up for a weekend where every run is an unforgettable journey through forests, across limestone plateaus, and under the towering peaks of one of France's most beautiful natural parks.
