Fond de Chaumont via Impasse des Chalets

At just 0.4km, Fond de Chaumont via Impasse des Chalets is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. A sustained 8.4% average gradient with a maximum of 10.7% 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.
