In der Reisbach via Alte Aachener Strasse

At just 1km, In der Reisbach via Alte Aachener Strasse is short but deceptively intense — 57m of elevation packed into a brief, breathless effort. The average gradient of 5.9% disguises ramps of 14.3% — 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 Wallonia, Belgium.
