Schönefelderstrasse via Hisselgasse

At just 1.5km, Schönefelderstrasse via Hisselgasse is short but deceptively intense — 65m of elevation packed into a brief, breathless effort. The average gradient of 4.5% disguises ramps of 9.3% — 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.
