Alto de La Cobertoria from Santa Marina via Cortes

The QU-5 rises 20.2km through rolling hills and mountain roads, gaining 795m to 1,177m. The average gradient of 3.9% disguises ramps of 10.7% — the kind of gradient that turns plans into prayers. This is a climb of endurance — the kind of effort measured in hours, where pacing matters more than power. Located in Asturias, Spain.
