Rue Nos Cisses from Heure-en-Famenne

At just 1.1km, Rue Nos Cisses from Heure-en-Famenne is short but deceptively intense — 61m of elevation packed into a brief, breathless effort. Averaging 5.7%, the road kicks to 9.5% at its steepest — a notable steepening that demands respect. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
