On October 17, 2026, runners will gather for the Jeongseon Donggang Marathon, an invigorating celebration of nature and community along the picturesque banks of the Donggang River. Nestled within Jeongseon County in South Korea, this event offers participants a unique blend of scenic beauty and cultural immersion. The race kicks off at 9:00 AM after assembly begins at 8:00 AM near the Jeongseon Ecology Experience Learning Center. The course winds through the serene landscape surrounding the Donggang River, offering runners stunning views of clear waters and rolling mountains as they traverse a series of out-and-back routes. Participants can choose from several distance options to suit their preferences: - A half marathon (21.0975 km) with a turnaround point near Gangnaru Farm. - A 10-kilometer race that loops around the designated course, turning back at its midpoint for breathtaking views of Kkulamgyo Bridge. - A family-friendly 5-kilometer fun run and couple's option to enjoy together. The event is meticulously organized by Roadsports in partnership with Eolleorirangkkae Co., Ltd. and supported by the Jeongseon County Council, ensuring a smooth experience for all participants. Registration opens on June 23, 2026, and early sign-ups are encouraged as capacity limits to the first 2,000 paid registrants apply. Runners will receive a technical T-shirt, sun visor, arm sleeves, and race bib upon registration. The half marathon and 10-kilometer races feature disposable timing chips for accurate results, while the shorter distances provide non-timed fun runs with all the same participant gifts. Immerse yourself in Jeongseon's natural beauty during this healing running festival that promises to be both a personal challenge and an opportunity to connect with fellow runners. Whether you're a seasoned marathoner or just starting out on your running journey, there is something for everyone at the 2026 Jeongseon Donggang Marathon. Participants are reminded of the importance of adhering to time limits: two hours and thirty minutes for the half marathon, one hour and thirty minutes for the 10-kilometer race, and a generous one-hour window for the shorter distances. This ensures that all runners can enjoy their experience while maintaining safety standards.
