Bois des Eyîs from Nassogne

At just 0.8km, Bois des Eyîs from Nassogne is short but deceptively intense — 66m of elevation packed into a brief, breathless effort. The average gradient of 8.7% disguises ramps of 18.3% — 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.
