Trails de la Brie des Morin

The Trails de la Brie 2026 is a premier nature running event held in the scenic Brie des Morin region of Seine-et-Marne. Scheduled for Sunday, May 3, 2026, the event offers five distinct routes starting from Saint-Cyr-sur-Morin. These races range from accessible 10.8 km trails for beginners to a grueling 61.9 km ultra-trail for seasoned athletes. The event is characterized by its "semi-self-sufficiency" philosophy, requiring runners to carry their own cups, and is deeply rooted in showcasing the historical and natural heritage of the Petit Morin valley, including old railway tracks and traditional Briard villages.

The 2026 edition features diverse distances and elevation profiles to suit all levels of trail runners and hikers. All races share a common finishing spirit in the heart of the village.

Saint-Cyr-sur-Morin is a charming rural commune in the Seine-et-Marne department, located approximately 75 km east of Paris. As of 2026, the village has a population of roughly 2,000 residents. The area is part of the historic Brie region, famous worldwide for its cheese production and its rolling agricultural plateaus. Demographically, the population is predominantly French/European, consisting of a mix of agricultural families and commuters who work in Meaux, Coulommiers, or the Greater Paris area. The local economy is balanced between traditional farming and green tourism, with a median household income of approximately €24,500 per year.

The local culture is defined by literary history and rural preservation. The village was the home of the famous writer Pierre Mac Orlan, and its identity is closely tied to the "Morin" river that carves through the landscape. Residents take great pride in their "Brie des Morin" identity, which is more rugged and forested than the flat plains of western Brie. The Trails de la Brie reflects this culture of "slow tourism" and physical effort, where the community comes together to welcome outsiders into their valley. The race often features local products at aid stations, reinforcing a culture that values artisan quality, heritage preservation (such as the "Tacot" railway history), and an active connection to the wooded slopes of the valley.

Runners can expect a high-quality technical experience with bib collection starting at 6:30 AM at the village hall. The courses are known for being surprisingly hilly for the Paris region, utilizing single-track forest paths and steep valley climbs. Because the race operates on a semi-self-sufficiency basis, participants enjoy a sense of autonomy while being supported by enthusiastic volunteers in the 11 villages along the route. Post-race facilities include showers and changing rooms at the local gymnasium, allowing athletes to recover and enjoy the festive atmosphere of the finish line in Saint-Cyr-sur-Morin.
