Hoge Berglaan & Leopold Decouxlaan

At just 1.1km, Hoge Berglaan & Leopold Decouxlaan is short but deceptively intense — 37m of elevation packed into a brief, breathless effort. The average gradient of 3.5% disguises ramps of 9.6% — 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.
