Alexey Lutsenko powered up the first summit finish of La Vuelta 2017 to take his maiden Grand Tour victory. The Kazakh rider attacked from the gun and dominated the 17-man break for a scintillating solo win ahead of Merhawi Kudus and Marc Soler. Behind, race leader Chris Froome attacked the group of favourites to retain the red jersey and further distance himself from his rivals. He now leads Tejay van Garderen by 10 seconds, with Esteban Chaves in third, 11 seconds back.
