Diriksberg from Sluizen

At just 1.1km, Diriksberg from Sluizen is short but deceptively intense — 42m of elevation packed into a brief, breathless effort. The average gradient of 3.7% disguises ramps of 8.6% — 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 Wallonia, Belgium.
