The Rennes School of Business Green Marathon 2025 is sold out!
A must-see sporting event in Brittany and recognised nationally, the Rennes School of Business Green Marathon returns on 25 and 26 October 2025. This new edition, for which Rennes SB is the title partner for the third year running, will once again bring together runners, walkers and sports enthusiasts for two days dedicated to performance, solidarity and the environment.
A unifying sporting event
For more than ten years, the Green Marathon has been one of the highlights of the autumn in Rennes. In 2025, participants will have the opportunity to take part in the various formats that make the event so rich:
- Marathon (42.195 km)
- Duo Marathon (teams of two)
- Relay Marathon (teams of four)
- 10 km Lamotte, festive night race
- Yves Rocher Women’s Race (5 km)
- Yves Rocher Family Walk (5 km)
With its 100% urban routes, the event is an invitation to (re)discover Rennes in a different way, in a friendly and unifying atmosphere.
An experience that goes beyond sport
The Green Marathon is not just a competition: it is a unique human experience. The entertainment, collective energy and encouragement from the public create an unforgettable atmosphere. It is also an important opportunity to promote the values of social responsibility championed by Rennes School of Business, demonstrating that sport can be a powerful vehicle for solidarity and commitment to the planet.
Registration closed and exchange platform
Registration for the 2025 edition is now full: all available bibs have been taken. For those who have already registered but are ultimately unable to participate, an official bib exchange platform has been set up by the organisers to enable the secure resale of places.
Participants will soon receive all the practical information they need about their race or walk. We look forward to seeing all the runners, walkers and spectators on 25 and 26 October 2025 to celebrate this great moment of sport, conviviality and environmental commitment.
