Cloetstraat

At just 1km, Cloetstraat is short but deceptively intense — 32m of elevation packed into a brief, breathless effort. The average gradient of 3.1% disguises ramps of 9.5% — 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 Flanders, Belgium.
