Join us from Saturday 13 September to Monday 15 September in Chamonix-Mont-Blanc as we pedal and putt toward a cure for Parkinson’s
Challenge yourself to steep alpine climbs, enjoy a more leisurely ride through the Chamonix valley, golf against the backdrop of majestic Mont Blanc and engage with Parkinson's experts as we raise critical funds for The Michael J. Fox Foundation for Parkinson’s Research, the single largest nonprofit funder of Parkinson’s research. 100% of all donations will go directly to Parkinson’s research programs.
More than 10 million people are living with Parkinson’s disease, the fastest-growing neurological condition in the world. Currently, there is no known cure for Parkinson’s, but we will hear about recent research discoveries that bring new hope for pathways to a cure.
Join the Chamonix Foxes for a weekend of cycling, golf, celebration and community as we work together to end Parkinson’s.

Featured Climbs
Col de la Colombière
Alt 1613m.
6km @ 6.8% average.
2020 Tour de France.
Upon leaving Cluses, once a watchmaking hub before production shifted to the Jura, the road climbs steadily through forested gradients of 4–7%, with occasional steeper ramps. It flattens briefly at Le Reposoir for a welcome break with some shade but then enters full sun and steeper climbing. The final 3 kilometers are brutal, averaging 9%, 10%, and 11%, but the views toward Annecy and Grand Bornand at the summit are well worth it.
Col des Aravis
Alt 1487m.
10km @ 5% average.
2020 Tour de France
The fast rolling road leads to St Jean de Sixt where the climb towards the Col des Aravis starts. After some friendly kilometers the road passes through the ski resort of La Clusaz where it ramps up to a steady 5-6%. Riders are advised to use this stretch to prepare their legs for the climbs still to come! The summit of the Col gives a breathtaking panorama across the Mont Blanc massif.
Col des Saisies
Alt 1658m.
14.5km @ 6% average.
2020 Tour de France.
A punchy start above 10% will wake up the legs as the road climbs steeply away from the Gorges d’Arly towards Col des Saisies, included in the 2025 Tour de France. Two sections of respite break up the otherwise relentless climb of 14km. Riders are advised to take the time to refuel and recover at the summit in Saisies ski resort as the road is not a descent all the way to the finish.
