Thier des Falises from Rochefort

At just 1.3km, Thier des Falises from Rochefort is short but deceptively intense — 86m of elevation packed into a brief, breathless effort. Averaging 6.5%, the road kicks to 10.3% at its steepest — a testing gradient that demands respect. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
