Marathon Médiéval de Seine-et-Marne

1st Edition — Sunday, May 10, 2026

Sunday, May 10, 2026, marked the launch of the Seine-et-Marne Medieval Marathon, the first edition of an annual event conceived by the Department. Runners set off from Place des Tours, in front of Blandy-lès-Tours castle, for a 42.195 km course through the Brie countryside to the medieval city of Provins, a UNESCO World Heritage site.

The course crossed nine communes and passed four major medieval sites: Blandy castle, Champeaux collegiate church, Cucharmoy church, and the Gallo-Roman theater of Châteaubleau. The arrival through Provins' Saint-Jean gate offered runners a spectacular finish at the foot of the ramparts.

Record Mobilization for a First Edition

In total, over 3,600 people participated in the various races over the weekend. Five formats were offered: marathon (42.195 km), Tours half-marathon (21.0975 km loop around Blandy), relay marathon (teams of 3 to 6 runners over 6 sections — sold out before the race), 5 km Knights and Princesses (non-timed festive race for teens and adults, organized on Saturday in Blandy and Sunday in Provins, costumes encouraged) and youth races (400 m / 850 m / 1,500 m depending on age, free). 200 volunteers were mobilized along the course, with 4 water stations and 3 full refreshment points highlighting local produce.

Medieval Entertainment on Both Sites

The weekend of May 9-10 featured medieval shows and music, producers' and artisans' markets, equestrian performances, fantastic parades, and immersive workshops (medieval hairstyling, tastings…). The patron of this first edition was Lorànt Deutsch, a writer and actor passionate about history.
