Krokelshaff from Aspelt

At just 1.5km, Krokelshaff from Aspelt is short but deceptively intense — 36m of elevation packed into a brief, breathless effort. The average gradient of 2.5% disguises ramps of 6.6% — 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.
