Côte de Courcelles from Route de Saint Lubin/Route de Gisors

At just 1km, Côte de Courcelles from Route de Saint Lubin/Route de Gisors is short but deceptively intense — 58m of elevation packed into a brief, breathless effort. The average gradient of 5.8% disguises ramps of 12.8% — 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 Picardie, France.
