The first is the Jaizkibel, 7.4 kilometers long at 5.8% and summits with 63 kilometers to go, with a rather technical descent afterwards. The second will be Erlaitz with it’s summit at 43Km to go, it averages over 10% for 4 kilometers, differences can be made, attacks can be dealt and serious damage can be created for the race’s outcome.
Over the last few years the crucial point has become the Alto de Murgil. the riders look to save their legs for the final 900 meters of the climb where the gradients are vicious, up to 18% - officially it is 2.0Km at 9.9%, and summits with 8 kilometers to go. From there on it's a mere descent and fast run-in back into the city center for the riders to cross the line.
