The Yeouido Kiwoom Run will be running on the public road, so there's no need to worry.
There's also a competition in Bunwon-ri?
Traffic control will be in effect from 07:30 for two hours.
The Tancheon Run has 5/10km events that go up and down.
Only the east side can go under Dundeokgyo Bridge, but
above it is a mountain road, so there will be about 3km of congestion.
After Dundeokgyo Bridge, you'll likely have to detour onto a nearby public road.

The Mapo competition's half course overlaps significantly with the public road.
Since it's a half marathon, think about allocating around 2 hours.
The Seongnae Creek competition also divides its course based on the starting point.
Both courses run in both directions on the road, so it might be a bit inconvenient.
The Dongjak competition starts near Nodeul Station, runs along Banpocheon Stream,
then returns to the Han River, passing by Seorae Island before returning.
