Hodinfosse via Rue des Larrons

At just 1.3km, Hodinfosse via Rue des Larrons is short but deceptively intense — 115m of elevation packed into a brief, breathless effort. The average gradient of 9% disguises ramps of 19.2% — 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.
