The 633 km route
The route starts at the Ara West Sea Lock in Incheon and links the Ara, Hangang, Namhangang, Saejae and Nakdonggang bike paths to the Nakdong River Estuary Bank in Busan, about 633 km in total. The Saejae section crosses a mountain pass, so it is not all flat riverside riding.
How certification works
- Booklet and stamps — you stamp a certification booklet at certification centres along the route. The Ara West Sea Lock start is one of them.
- Mobile option — the Ministry of the Interior and Safety’s bicycle portal maintains a certification booklet app.
- Completion — once every stamp is collected, you apply for the completion certificate and medal.
Where to buy the booklet, centre locations and hours, and how to apply for the medal can change, so check the operator’s current notice before you go. Missing a single stamp can mean backtracking, which is why many riders pin every centre on their map in advance.
Days by daily distance
| Per day | Days for 633 km | Who it suits |
|---|---|---|
| 60 km (37 mi) | about 11 | Few long rides so far, sightseeing pace |
| 80 km (50 mi) | about 8 | Regular weekend long rides |
| 100 km (62 mi) | about 7 | Has done several 100 km days |
| 130 km+ (80 mi+) | around 5 | Trained riders, if accommodation lines up |
Adjust around where you can sleep and around the pass: shorter on the climbing day, longer on the flat Nakdong River stretch.
Training before you go
For a 100 km-a-day plan, ride at least one 100 km day before the trip, and ideally two long days back to back. Build weekly distance gradually and note how you feel the next morning; that note becomes your guide for daily distance on the route.
Logging training and the trip

Track training against landmarks
Landmark progress on the Stats tab of Daily Bike Log includes the Century ride (100 km), Seoul to Busan (straight line, 325 km) and “Korea Four-Rivers route” at 633 km, the same distance as the cross-country route. Your training total shows as a percentage of it.
During the trip, one entry per day
At each night’s stop, enter that day’s distance and the section in the memo, for example Chungju to Mungyeong. Consecutive days also build your streak.

Earn the century badge first
Badges / Achievements includes a 100 km single-day badge and a 633 km total badge. Getting the single-day century during training is a good confidence check.

FAQ
Is the app’s “Four-Rivers” landmark the same route?
Its 633 km matches the Incheon to Busan cross-country distance. Follow the operator for the official route names and sections.
Does the app count as certification?
No. It is a personal log; official certification comes only from the booklet or the official app.
Can I ride it in winter?
Ice and short days cut your daily distance. See winter riding and recalculate.
