Basiliek van Scherpenheuvel

At just 0.5km, Basiliek van Scherpenheuvel is short but deceptively intense — 25m of elevation packed into a brief, breathless effort. Averaging 4.8%, 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 Flanders, Belgium.
