Paul da Serra from Ribeira Brava

Paul da Serra from Ribeira Brava is one of cycling's great tests — 18km of sustained climbing, gaining 1,526m from base to summit. The average gradient of 8.5% disguises ramps of 18.2% — the kind of gradient that turns plans into prayers. The 3 hairpin turns break up the climb, each one revealing a new perspective on the road ahead. The road reaches 1,575m — high enough to feel the altitude on tired legs. Located in Madeira, Portugal.
