Rua Infante Dom Henrique via Rua do Poço

At just 1.6km, Rua Infante Dom Henrique via Rua do Poço is short but deceptively intense — 121m of elevation packed into a brief, breathless effort. The average gradient of 7.5% disguises ramps of 15.1% — the kind of gradient that turns plans into prayers. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Lisbon, Portugal.
