The 2026 Oak Tree Run invites runners, walkers, stroller pushers, and wheelchair users of all skill levels to explore the scenic Ttukseom Hangang Park on Sunday, October 25, 2026. Located along the Han River in Seoul, this event offers three distance options: a family-friendly 5K, an energizing 10K, or a challenging half-marathon (21K). Registration is open until September 29, 2026, with entry fees set at 50,000 won per participant. Groups of up to six can register together for convenience. Participants will enjoy the picturesque riverfront setting as they start their race at 9:00 a.m., winding through lush green spaces and along the tranquil waters of Hangang Park. All finishers receive a commemorative medal and an Oak Tree Run T-shirt, while those completing the longer distances (10K and half-marathon) also earn a digital certificate with their official finishing time. The race is not just about crossing the finish line; it's about making a difference in the lives of young Korean scholars. Proceeds from this event support the Oak Tree Project, which aims to provide scholarships and mentoring for students who have transitioned out of orphanages and are pursuing higher education. Join runners from around Korea as they come together to celebrate community spirit while contributing positively to society. For more information or to register, visit the official website where you can find details on race day logistics, such as parking and transportation options. Participants should note that T-shirts will only be given out to those who have registered in advance and attend the event. This ensures a seamless experience for all runners while supporting this vital cause.
