Infini'Flamme Trail is a trail race held in April in Luynes, located in France's Indre-et-Loire department within the Centre-Val de Loire region. The Ouest Agglo firefighters' association organizes the event, which features a distinct format: participants select short, loop-based trail courses instead of a conventional point-to-point race. Available distances are 6.6 km, 13.2 km, and approximately 19 km. The 13.2 km race consists of two loops, while the longer XXS option comprises three loops.
The course offers moderate climbing, avoiding flatness, with roughly 122 m of elevation gain over 13.2 km and about 183 m for the longer distance. The race commences in the late afternoon, establishing a different pace compared to typical morning trail events. Its initial character emphasizes patience and endurance over pure speed; local reporting described it as a tribute to slowness and perseverance. Cédric Gontier was the primary victor in the inaugural edition.
