Duelemerbierg from Ellange

At just 1.2km, Duelemerbierg from Ellange is short but deceptively intense — 58m of elevation packed into a brief, breathless effort. The average gradient of 4.7% 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 Grevenmacher, Luxembourg.
