Côte de Berteaucourt from Berteaucourt Les Thennes

At just 1.5km, Côte de Berteaucourt from Berteaucourt Les Thennes is short but deceptively intense — 63m of elevation packed into a brief, breathless effort. The average gradient of 4.1% disguises ramps of 10.1% — 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 Picardie, France.
