Frennetstrasse via Bergfeld

At just 1.5km, Frennetstrasse via Bergfeld is short but deceptively intense — 55m of elevation packed into a brief, breathless effort. The average gradient of 3.7% disguises ramps of 9.8% — 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, Germany.
