The Rennes Green Marathon: a fast course for a sustainable cause

Combining personal challenge with global reforestation is the promise of this major running event held each autumn in Ille-et-Vilaine. Renowned for its smooth flow and lack of elevation gain, the course leads the pack through the historic lanes and landmark monuments of Brittany’s capital. The schedule is designed to be inclusive, offering daytime and nighttime formats ranging from 5 km to the legendary marathon distance. Driven by the warm encouragement of a passionate crowd, every finish-line crossing celebrates both individual athletic achievement and a tangible step in support of the environment.
