Our solidarity bibs
Another way to support us
Charity bibs make it possible to secure a place in many races throughout the year, while giving real meaning to the challenge. Each entry directly supports research into serious diseases linked to ultra-endurance.
The donation linked to the bib may qualify for a 66% tax reduction, up to 20% of taxable income, in accordance with current regulations.
