Côte d'Aidling

At just 1.4km, Côte d'Aidling is short but deceptively intense — 63m of elevation packed into a brief, breathless effort. The average gradient of 4.5% disguises ramps of 12.5% — 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 Lorraine, France.
