Le Marathon Vert Rennes School of Business 2026

The Marathon Vert Rennes School of Business is an October running festival in Rennes, Brittany, centered on a fast urban marathon rather than a single event. The program offers six options: a solo marathon, a duo marathon, a relay, a 10 km, a women’s 5 km, and a family walk. The city course is quick enough to place Rennes among France’s faster running events. The weekend attracts club runners, first-timers, relay teams, walkers, and families. Established in 2011, the series has developed over approximately fifteen years, recently registering 18,590 participants across its races. It maintains a distinct environmental focus alongside its lively crowd support.
