Hierschtbierg from Pétange

At just 1.4km, Hierschtbierg from Pétange is short but deceptively intense — 97m of elevation packed into a brief, breathless effort. The average gradient of 7.1% disguises ramps of 15.6% — 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.
