Merzigerwee from Clemency

At just 1km, Merzigerwee from Clemency is short but deceptively intense — 37m of elevation packed into a brief, breathless effort. The average gradient of 3.7% disguises ramps of 8% — 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.
