The world famous (and feared) Angliru is just west of the Pyrenees. The 12.5-kilometre-long climb has an average incline percentage of 10.1%. Because the first half of the climb only rises by 7.6%, the second part is particularly hard: its steepest section is 23.6%! This is no mountain for an untrained cyclist. If you want great weather, though, don’t go to the Asturias, as this region is called. The cool, maritime climate ensures that temperatures change very little, even in the summer. In the winter, people are not surprised by snowfall, and it rains in the summer. The cycling season in this area is therefore similar to that in the Netherlands.
