Allows you to quickly and safely connect Jouy and Bièvre. For gravel/mountain bikes, it is more pleasant to take the path that passes through the fields along the INRA.

Beautiful climb of almost 2km (longest in the area) at an average gradient of 5%. Residential area in the first part then wooded section in the second part. There is a traffic light on the route but not too disturbing because you don't cross the road in the direction of the climb.
