Resources
We keep this site practical and current, but you should know the primary sources too. Last verified: 2026-07-17.
Official
The primary sources — route data, certification rules, medal orders.
- bike.go.kr (자전거행복나눔)
The government cycling portal: route maps, certification center list, passport rules. Korean-first; the English pages are thinner and less current.
- bike.go.kr — English
Official English pages on the certification system and passport. Good for rules, weak on maps.
- 우리강 이용 도우미 (riverguide.go.kr)
Where completion medals are ordered after your passport is verified. Korean payment methods and domestic delivery only — see our certification guide for workarounds.
- K-water O&M (케이워터운영관리)
The K-water subsidiary that operates many weir certification centers. Center operating notices sometimes appear here first.
