Kiem / Stengerner Bësch from Welfrange

At just 0.9km, Kiem / Stengerner Bësch from Welfrange is short but deceptively intense — 59m of elevation packed into a brief, breathless effort. The average gradient of 6.5% disguises ramps of 13.1% — 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 Grevenmacher, Luxembourg.
