How it works


Over 4 days, you will ride up to 400km across some of the toughest mountain climbs of the 2025 Tour de France, with cyclists from all over the world.

You will become part of cycling history as you take on the legendary Tour de France mountains, which in previous years have included Galibier, Cime de la Bonnette and Col de Vars. Imagine tackling these climbs before Pogacar, Rogli? and Evenpoel!


The MSIF team and our dedicated coaches will be there to support you every step of the way. You'll receive training support, fundraising tips and have the opportunity to meet your fellow riders at our regular online meetings.


The funds you raise will enable us to collaborate with our members across the world to improve the quality of life and wellbeing of everybody affected by MS. Every turn of the crank will bring us closer to a world without MS.
