Auf der Houscht from Kalkesbach

At just 0.5km, Auf der Houscht from Kalkesbach is short but deceptively intense — 48m of elevation packed into a brief, breathless effort. A sustained 9% average gradient with a maximum of 12.6% makes this a steady and demanding ascent. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Grevenmacher, Luxembourg.
