Trail Cloysien des 3 Rivières

Celebrate a 15-year legacy on a spectacular private estate at the Trail Cloysien des 3 Rivières in Cloyes-les-Trois-Rivières on March 1, 2026. This cherished anniversary edition offers two distinct adventures: a technical 21km "Semi-Trail" and a more accessible 10km "Discovery" route, both starting and finishing at the majestic Château de Montigny-le-Gannelon. Runners are granted exclusive access to traverse normally private lands, experiencing a thrilling mix of steep climbs—including the legendary "Marches de Montigny"—technical single-track, and refreshing river crossings. The atmosphere is one of local pride and exclusive discovery, where the entire community comes together to create a unique and challenging trail experience.

More than just a race, it's an invitation to explore a hidden, bucolic landscape that remains off-limits for reconnaissance, ensuring race day delivers genuine surprises around every bend. The event masterfully balances a serious athletic test with festive, family-friendly elements, including youth races in the château park and a generous post-race buffet. It’s a chance to be part of a storied local tradition, to test your skills on a truly original and demanding course, and to enjoy the warm, authentic hospitality of the Loir-et-Cher region. Prepare for a trail that feels both classic and full of new secrets.
