Steepest Gradients by Distance
Steepest kilometer starts at km 13.5 (13%)
DangerousRoad.com says of this road:
“Alto del Gamoniteiro is a high mountain pass at an elevation of 1,782 m above the sea level, located in the Autonomous Community of the Principality of Asturias, Spain. The road to reach the summit is extremely narrow, with a terrible asphalt, potholes and extremely steep. The ramps really hit hard, getting up to 15% at the end of three, ascending in difficulty, 3km from home, a flattening out for no more than 100m is then followed by a spike up to 13%. The last 1.5 km is also the toughest, averaging no less than 12%, and with a maximum of just 17% that tells you that it's incessant suffering. It's actually kind of strange that the maximum of such a brutal climb is just 17%.
There are 2 routes to reach the summit. Starting from Pola de Lena, the ascent is 15.9 km long. Over this distance, the elevation gain is 1450 height meters. The average percentage is 9.1 %. And starting from San Martin, the ascent is 17 km long. Over this distance, the elevation gain is 1290 height meters. The average percentage is 7.6 %.” DangerousRoads.org
