Lisogne via Thynes

At just 1.8km, Lisogne via Thynes is short but deceptively intense — 64m of elevation packed into a brief, breathless effort. The average gradient of 3.5% disguises ramps of 8.5% — 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.
