Bois des Maréchaux from Silenrieux

At just 1km, Bois des Maréchaux from Silenrieux is short but deceptively intense — 75m of elevation packed into a brief, breathless effort. A sustained 7.6% average gradient with a maximum of 9.5% makes this a remarkably consistent and demanding ascent. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
