Mierenberg via Patattestraat

At just 1.2km, Mierenberg via Patattestraat is short but deceptively intense — 34m of elevation packed into a brief, breathless effort. The average gradient of 2.8% disguises ramps of 5.8% — 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.
