Wilgenbaan from Mierendonk

At just 1.4km, Wilgenbaan from Mierendonk is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. The average gradient of 2.5% disguises ramps of 6.7% — 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.
