A solidary Marathon
The Mont Blanc Marathon supports the causes that are close to its heart!
Supporting Patients and Medical Research
Through its charity race bibs, the Mont-Blanc Marathon is committed to supporting three organizations that work to assist patients and advance medical research:
- Vaincre les Maladies Lysosomales, an organization that supports the 3,000 people in France affected by one of the 53 lysosomal diseases—rare genetic disorders that cause severe multiple disabilities.
In 2026, €30,200 was raised for the organization.
- Trail Runners Against Muco, a Chamonix-based nonprofit that has been taking on extraordinary athletic challenges for over 20 years to raise funds for Vaincre la Mucoviscidose.
- Ultra Sports Science, a nonprofit endowment fund that helps finance medical research into serious diseases affecting athletes, with the goal of better understanding and preventing them.
In 2026, 115 charity race bibs will be sold to benefit our three partners.
Bringing exceptional projects to life for Chamonix's young athletes
Since 2016, we have been selling bibs, the proceeds of which are used to finance exceptional sporting projects for children who are members of the Club des Sports sports sections.
Thanks to the €70,000 raised in 2025, nearly 300 young people from 12 sports sections have been able to carry out sporting projects that they would not otherwise have been able to: team-building or discovery courses, participation in tournaments and competitions, meetings with top athletes, etc.
In 2026, 160 solidarity bibs will be sold to benefit the sports sections of the Chamonix Sports Club.
MORE INFORMATION ON SOLIDARITY BIBS
The Club des Sports de Chamonix is a non-profit association under the French Law of 1901. A donation made to the Club des Sports therefore enables runners who buy a solidarity bib and who are taxable in France, to benefit from a tax reduction of 66% of the amount of the donation, up to a limit of 20% of their taxable income. The Club des Sports de Chamonix can provide a tax receipt.
Promoting inclusion and social diversity
The Mont-Blanc Marathon is a unique opportunity to bring solidarity to life and to promote the values of inclusion and social mix espoused by the Club des Sports. We are working with 2 social and socio-medical organizations to make volunteering accessible to all:
- The association Aller plus Haut, located in Sallanches, which supports adults with disabilities,
- The EPDA de Prévention spécialisée, located in Chamonix, which provides educational support for young people in difficulty.
