Rue des Monthys via Rue des Hauts Prés

At just 1.7km, Rue des Monthys via Rue des Hauts Prés is short but deceptively intense — 59m of elevation packed into a brief, breathless effort. The average gradient of 3.4% disguises ramps of 7.5% — 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.
