Montagne de l'Invasion

At just 0.6km, Montagne de l'Invasion is short but deceptively intense — 63m of elevation packed into a brief, breathless effort. At 11% average, every metre is earned. The steepest sections touch 13.1%, 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.
