Col de Serrières via Serrières

At just 1.2km, Col de Serrières via Serrières is short but deceptively intense — 44m of elevation packed into a brief, breathless effort. The average gradient of 3.6% 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 Lorraine, France.
