Buchstrasse via Atherstrasse

At just 1km, Buchstrasse via Atherstrasse is short but deceptively intense — 63m of elevation packed into a brief, breathless effort. The average gradient of 6.3% disguises ramps of 14.9% — 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.
