Kesselbierg from Bettembourg

At just 1.3km, Kesselbierg from Bettembourg is short but deceptively intense — 37m of elevation packed into a brief, breathless effort. The average gradient of 2.9% disguises ramps of 7.2% — 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 Luxembourg, Luxembourg.
