Light On Tri Madine is a popular annual triathlon event held each September at the scenic Lac de Madine in northeastern France, nestled between Metz and Nancy. Designed for athletes of all levels, the event offers three main race formats: S (500 m swim, 20 km bike, 5 km run), M (1,500 m swim, 40 km bike, 10 km run), and L (1,900 m swim, 85 km bike, 21 km run), each taking place over a weekend of competition. The courses span calm lake waters, rolling countryside bike routes through the Côtes de Meuse, and mostly flat run paths around the lake. In addition to adult categories, Light On Tri Madine also hosts youth races, creating a welcoming and family-friendly atmosphere. With its mix of competitive challenge and natural beauty, it has become a favorite destination for both seasoned triathletes and newcomers to the sport.
