No respite as the race arrives in Bizkaia after 3 stages. The cyclists will once again encounter 7 mountain passes, including the Category 1 Izua pass. A climb that will undoubtedly decide who wins the stage and even make a difference in the general classification. The climb will not follow the main road nor the Krabelin to Arrate ascent but depart from the Matsaria industrial estate on a very narrow road between farmhouses with 20% gradients.
