Constitution Hill via Bullin's Lane

At just 0.8km, Constitution Hill via Bullin's Lane is short but deceptively intense — 63m of elevation packed into a brief, breathless effort. The average gradient of 8.4% disguises ramps of 20.3% — 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 Wales, Wales.
