A solidary Marathon

The Mont Blanc Marathon supports causes close to its heart!

Supporting patients and medical research

Through its solidarity bibs, the Mont Blanc Marathon is committed to 3 organizations working to support patients and medical research:

  • Vaincre les Maladies Lysosomales, an association that supports the 3,000 French people affected by one of the 53 lysosomal diseases, rare genetic diseases that cause multiple disabilities.
  • Trail Runners Against Muco, an association based in the Chamonix region, which for over 20 years has been taking on extraordinary sporting challenges to raise funds for Vaincre la Mucoviscidose. In 2025, 30 bibs were allocated to the association. Thanks to the commitment of their ambassadors, €37,215 was raised for Vaincre la Mucoviscidose.
  • Ultra Sports Science, a non-profit endowment fund that helps finance medical research into serious illnesses affecting athletes, to better understand and prevent them.

Buying a solidarity race number means you can register for one of the Mont Blanc Marathon races without going through the draw, while making a direct donation to one of our partner organizations and raising awareness of an important cause.

In 2025, 125 solidarity bibs will be sold for the benefit of our 3 partners.
