is at 4.6%, a height gain of . Writing in Vélo, Gilbert Duclos-Lassalle said: The Aubisque is one of those hors catégorie cols that make the legend of the Tour. The climb is in three parts. The first is fairly easy. The road is good and the specialists use 39 × 19 or 53 × 21. Then, at Eaux-Bonnes, you turn left and get to the real climb. This part, as far as Gourette, is a lot more difficult. The hardest part swings between eight and ten per cent from the seventh kilometre until Pont-du-Goua at the ninth kilometre and you need 39 × 21. Then, after 300m of flat in Gourette, a hairpin goes up to the Hôtel des Crêtes Blanches. Riders use 39 × 17 over four kilometres before going into 39 × 16 in the last two kilometres. Tour de France The Col d'Aubisque appeared in the Tour de France in 1910, crossed by François Lafourcade. It has appeared frequently since then, more than once every two years.

Steinès visited the man responsible for local roads, the ingénieur des ponts-et-chaussées, who said: "Take the riders up the Aubisque? You're completely crazy in Paris." Steinès agreed that the Tour would pay 5,000 francs to clear the pass. Desgrange knocked the price down to 2,000. In 1951, Wim van Est was in the yellow jersey – the first Dutchman to wear it and chasing the leaders towards the Soulor when he slipped on gravel and fell into a ravine. He said: That first bend was wet, slippery from the snow. And there were sharp stones on the road that the cars had kicked up, and my front wheel hit them and I went over. Well, there was a drop of 20m. They've built a barrier there now but then there was nothing to stop you going over. I fell 20 metres, rolling and rolling and rolling. My feet had come out of the straps, my bike had disappeared, and there was a little flat area, the only one that's there, no bigger than the seat of a chair, and I landed on my backside. A metre left or right and I'd have dropped onto solid stone, six or seven hundred metres down. My ankles were all hurt, my elbows were
