From Mauléon-Barousse, this 19-kilometer hors catégorie climb is completed in three stages. The first seven kilometers are fairly straightforward, then the next seven become more complicated, before culminating in a grand finale with the last five at over 9%. Even more so than on other passes, the key here is economy.
