Charity bibs

The sale date for the 2025 health, environment and solidarity bibs will be announced shortly.

The purchase of one of these bibs is an opportunity for runners to guarantee their registration for one of the Mont-Blanc Marathon races (without random draw), while contributing to a useful and impacting project:

Help Chamonix's young athletes carry out extraordinary projects!

Since 2016, the Chamonix Sports Club is offering solidarity bibs to fund exceptional projects for children members of sports sections.

In 2024, 140 solidarity bibs (divided between the Duo Etoilé, 42km, 23km and 90km du Mont-Blanc) were offered for sale, raising €70,000 ! The amount collected was divided between 13 sports sections, whose projects were selected by a committee:

Climbing Trip to Buis les Baronnies :

"Many thanks to the runners who bought a solidarity bib! Without you, the 19 young climbers from the climbing section of the Club des Sports de Chamonix would not have been able to make their incredible trip to Buis les Baronnies. 13 of the climbers, aged between 8 and 10, were traveling for the 1st time with the club outside the valley, and were discovering climbing in a natural environment. The other 6 were older teenagers, at the start of their journey towards a climbing diploma. The trip gave these teenagers their first experience of supervision, as they helped the climbing instructors to supervise the younger climbers. The trip also raised the group's awareness of the ecology of local cliffs and how to climb in a way that respects local wildlife."

Hockey: Easter Cup tournament in the Czech Republic.

"Following the 2 trips to Garmisch, which were made possible thanks to the Marathon's solidarity bibs, the Club has forged relationships with the field hockey club and the Garmisch secondary school to hopefully enable future exchanges and sporting encounters. The event was a great success and we hope to continue building our friendship over the coming years."
Korean Martial Arts: cohesion course in Germany.
Soccer : "Copa Maresme" tournament in the Costa Brava.
Swimming : intensive course in Piombino, Italy.
Ski jumping: course and exchange with a ski jumping club in Einsideln (Switzerland).
Alpine skiing: zero-carbon ambition course in Zermatt (Switzerland).
Cross-country skiing: physical preparation course in Planica (Slovenia).
Snowboard : multi-slide cohesion course and skateboard challenge in Sallanches.

Support medical research and patient care!

Vaincre les Maladies Lysosomales (Overcoming Lysosomal Diseases)

Since 2013, the Mont-Blanc Marathon has joined forces with the association Vaincre les Maladies Lysosomales, which is recognized of public utility, enabling people affected by one of the 60 lysosomal diseases to make their voices heard and pool investment in scientific and medical research.

VML is based on one ultimate goal: to cure people suffering from lysosomal diseases. The association has therefore set itself three missions for the benefit of the greatest number of people:

Advance research and improve access to care;
Provide certified and appropriate scientific and medical information;
Support and help families adapt to illness and disability.

In 2024, the Mont-Blanc Marathon offered 56 charity bibs in support of VML, divided between the Duo Etoilé, 10km, 23km, 42km and 90km Mont-Blanc races.

Trail Runners Against Muco

The Mont-Blanc Marathon has joined forces with Trail Runners Against Muco in the fight against mucoviscidosis, a genetic disease that mainly affects the respiratory and digestive systems.

For over 20 years, the Chamonix-based association Trail Runners Against Muco has been facing sporting challenges to raise funds for Vaincre la Mucovicidose. These challenges can be virtual, such as crossing the American continent in 2014 (22,950€ raised), or real, such as taking part in the Mont-Blanc 23km in 2023 (23,546€ raised).

Their motto: "Let's give our breath to those who lack it, and together let's win life!"

By supporting Vaincre La Mucoviscidose, Trail Runners Against Muco contributes to the following objectives:

Raise funds to support medical and scientific research aimed at finding more effective treatments and, ultimately, a cure for mucoviscidosis,
Improve patients' quality of life by offering them appropriate support, helping them to manage their disease on a day-to-day basis, and providing them with social and psychological support.
Raise awareness and inform the general public about the disease and its challenges.

In 2024, the Mont-Blanc Marathon offered 20 bibs for TRAMUCO, divided between the Duo Etoilé, the 23 km, the 42 km and the 90 km of the Mont-Blanc.

Ultra Sports Science

The Mont-Blanc Marathon has joined forces with Ultra Sports Science to support medical research into ultra-endurance sports.

Created in 2015, Ultra Sports Science aims to:

Raise funds to set up international medical research,
Transmit the results of this research to athletes, scientists, doctors, organizers and sports federations,
Implement a health policy to prevent doping.

In 2024, the Mont-Blanc Marathon offered 32 health bibs in support of Ultra Sports Science, spread over the 90km, 42km and 23km.

Help protecting our environment!

Since the creation of the Mont-Blanc Cross in 1979, the Chamonix Sports Club has been working to offer quality races while limiting their impact on the environment.

Today more than ever, climate and environmental issues are at the heart of our concerns. Through the sale of environmental bibs, our aim is to participate in an ecological movement that goes beyond the event framework and have a positive impact on the planet.

In 2024, we offered 35 environmental bibs, spread across the Duo Etoilé, 23km, 42km and 90km Mont-Blanc races. The funds raised through these donations will directly contribute to financing local environmental initiatives.

The Club des Sports de Chamonix is a non-profit association created under the French Law of 1901. The association can provide proof of donation to lighten the tax burden. In France, the donor benefits from a tax deduction of 66% of the amount donated, up to a limit of 20% of taxable income.
