Houselsbierg from Hellange

At just 0.7km, Houselsbierg from Hellange is short but deceptively intense — 35m of elevation packed into a brief, breathless effort. The average gradient of 4.9% disguises ramps of 11.3% — the kind of gradient that turns plans into prayers. It's over before the legs know what happened — a short, explosive effort where momentum is everything. Located in Luxembourg, Luxembourg.
