Montée du secteur de Wihéries via Bas des Rocs

At just 1.1km, Montée du secteur de Wihéries via Bas des Rocs is short but deceptively intense — 43m of elevation packed into a brief, breathless effort. The average gradient of 4.1% disguises ramps of 11.1% — 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 Wallonia, Belgium.
