Côte d'Ernster

At just 0.7km, Côte d'Ernster is short but deceptively intense — 41m of elevation packed into a brief, breathless effort. The average gradient of 5.9% disguises ramps of 13.2% — 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.
