Bois de Mariemont via Rue de l'Olive

At just 0.6km, Bois de Mariemont via Rue de l'Olive is short but deceptively intense — 33m of elevation packed into a brief, breathless effort. The average gradient of 5.7% disguises ramps of 12.3% — 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.
