20. One of the most famous climbs in the Vuelta is the Alto de el Angliru. What is thought to be the steepest gradient that this climb reaches?
From Quiz Vuelta a Espana
Answer:
23.6%
The Alto de el Angliru reaches a staggering 23.6% gradient, three kilometres from the peak of the summit, making it one of the steepest climbs in road racing in Europe. This climb is 12 kilometres long, and the first half of the climb isn't really demanding for professional riders at all. However, from the 6km mark, the average gradient is 13.1%, and after the 23.6% ramp, there are two more ramps with gradients between 18% and 21%. This climb is one of the most feared, despite only being used for the first time in the Vuelta in 1999. Jose Maria Jimenez, Gilberto Simoni, and Roberto Heras, have all won on this climb. In 2003, heavy rain meant a lot of problems when the ascension to the summet of the Angliru began, meaning that race organisers have considered scrapping this climb from the Asturias region of Spain.
