Rocher du Faix du Diable

At just 1km, Rocher du Faix du Diable is short but deceptively intense — 62m of elevation packed into a brief, breathless effort. Averaging 6%, the road kicks to 9.5% at its steepest — a notable steepening that demands respect. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
