Roiseleux via L'Engin

At just 0.8km, Roiseleux via L'Engin is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. The average gradient of 4.3% disguises ramps of 9.1% — 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.
