Route de Thy-le-Château via Rue des Gradins

At just 0.8km, Route de Thy-le-Château via Rue des Gradins is short but deceptively intense — 40m of elevation packed into a brief, breathless effort. The average gradient of 5.3% disguises ramps of 10.8% — 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 Wallonia, Belgium.
