This side is characterized by deep soils, a tunnel with a bend and a beautiful view over the green meadows. At 2.5 kilometers from the top is a plaque on the left in memory of the Dutchman Wim van Est. He was the first Dutchman to wear the yellow jersey in the Tour of France, but slipped in the descent of the Col de l’Ausbisque wearing the yellow jersey. He fell 70 meters, survived, but did lose the yellow jersey that day. He he had to be pulled back on the road with 40 tied up racing tires. Footage on his rescue showed up for the first time in 1992. The Global Cycling Network mentioned him in a video, as one of the toughest riders of all times.
