On this 17km-long stage, you mainly cycle on bike paths, and from time to time along roads shared with cars, without much traffic
This stage is for cyclists who are fit, as you have to tackle some tricky slopes (especially in Loges-en-Josas).
Pay attention passing on the D195 in Magny-les-Hameaux, because of dense traffic (70km/h - in red on the map). A bike lane will be built in the future.
Between Magny-les-Hameaux and Saint Rémy-lès-Chevreuse, pay attention to the Chemin de la Butte aux Buis which is a steep slope with stairs, we advise to continue by foot. Improvement to come.
