Keijenbergseweg from Renkum

At just 1.6km, Keijenbergseweg from Renkum is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. The average gradient of 2.2% disguises ramps of 4.5% — 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 Gelderland, Netherlands.
