About Col de la Loze
The Col de la Loze (2304 m) above Méribel has only been on the Tour de France route since 2020. The last kilometres follow a narrow cycle road with changing, very steep ramps.
In rampida you ride the route exactly as it lies on the road: the gradient reaches your trainer metre by metre, the scenery is built from real elevation data and OpenStreetMap. A pacer group can pull you along, and next time you race your own ghost.
