La Spinette from Aisemont

At just 0.5km, La Spinette from Aisemont is short but deceptively intense — 57m of elevation packed into a brief, breathless effort. At 10.5% average, every metre is earned. The steepest sections touch 15%, where the road feels more wall than road. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Wallonia, Belgium.
