Cyclosportive from Saint-Michel-de-Maurienne over four climbs to the Col du Galibier (2,642 m): 110 km with about 3,300 m of climbing on Sunday 6 June 2027, alongside a 35 km Grimpée and a 75 km Rando on Saturday 5 June.
What this race demands
This 110 km ride combines 3,350 m of climbing with four climbs, finishing at the 2,642 m Col du Galibier. It demands sustained climbing ability and enough endurance to manage a long day in the saddle.
Climbing volume
With 3,350 m of elevation gain over 110 km, climbing makes up a substantial part of the ride. Athletes need to sustain effort across repeated ascents rather than rely on a single climb.
High-altitude effort
The route reaches the Col du Galibier at 2,642 m. Riders should be prepared for the demands of continuing to climb at high elevation.
Long-ride endurance
The distance and elevation together point to several hours of riding for most participants. Endurance and sensible pacing will matter across the four climbs.
For a ride likely to last well over 2.5 hours, aim for about 60–90 g of carbohydrate per hour.
