An der Hierchen from Aasselburermillen

At just 1.7km, An der Hierchen from Aasselburermillen is short but deceptively intense — 82m of elevation packed into a brief, breathless effort. Averaging 4.8%, the road kicks to 8.3% 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 Ardennes, Belgium.
