Rue du Puits via Rue Vaudaigle

At just 1.3km, Rue du Puits via Rue Vaudaigle is short but deceptively intense — 59m of elevation packed into a brief, breathless effort. The average gradient of 4.7% disguises ramps of 10.4% — 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.
