Race Information
K-RUN Challenge is a race where you can enjoy an autumn marathon while running along the Han River. The race starts at 9:00 a.m., and check-in takes place at 8:00 a.m. on the same day.
The start area is the waterfront plaza of Ttukseom Hangang Citizens' Park, and the course runs from the Ttukseom Hangang Citizens' Park waterfront plaza to just before Gangdong Bridge. It offers three events—half marathon, 10 km, and 5 km—so you can choose the distance that fits your fitness and goals.
The entry fees are KRW 60,000 for the half marathon, KRW 55,000 for the 10 km, and KRW 40,000 for the 5 km. The half marathon and 10 km also have separate “maniac” entry fees, and maniac participants do not receive the official souvenir.
Participants receive an official souvenir, bib number, finisher medal, certificate, snacks and drinks, and a timing chip. Team entries are available for groups of two or more, and teams of 20 or more receive one booth and a banner. Anyone in good physical condition, male or female, can participate.
