Dumberg via Karrenbergstraat

At just 0.6km, Dumberg via Karrenbergstraat is short but deceptively intense — 35m of elevation packed into a brief, breathless effort. The average gradient of 5.6% disguises ramps of 15% — 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.
