La chapelle du Try-au-Chêne

At just 1km, La chapelle du Try-au-Chêne is short but deceptively intense — 58m of elevation packed into a brief, breathless effort. Averaging 5.8%, the road kicks to 9.9% 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.
