Haksberg via Donkstraat

At just 1.2km, Haksberg via Donkstraat is short but deceptively intense — 30m of elevation packed into a brief, breathless effort. The average gradient of 2.5% disguises ramps of 7.8% — the kind of gradient that turns plans into prayers. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Flanders, Belgium.
