On October 5, 2026, runners from all over Korea will gather at the Second Campus of Tech University of Korea for an exciting race day. Located in Siheung City, Gyeonggi-do, this vibrant campus offers a picturesque setting with modern facilities and lush greenery. Registration opens on July 22, 2026, at 2:00 PM, offering spots to the first 5,000 participants across three race categories. The half marathon (42.195 km) starts at 9:00 AM with a recommended time of two and a half hours, while the 10-kilometer run follows immediately after, aiming for completion within one hour thirty minutes. A shorter yet equally engaging option is the 5-kilometer race, designed to cater to all ages. Participants in both the half marathon and 10 km races will receive a Diadora running belt bag as part of their registration package. The 5 km entrants are rewarded with an exclusive gift: three kilograms of Haettomi rice and a KRW 5,000 Siru local voucher. All runners can expect to be provided with essential items such as race bibs, timing chips (for the half marathon and 10-kilometer races), finisher medals, mobile result certificates, and refreshments. The event is organized by the Siheung City Sports Council in collaboration with Kyeonggi Ilbo and the Siheung City Athletics Federation. It benefits from support from various local entities including Siheung City, the Siheung City Council, Siheung Police Station, and Tech University of Korea itself. Assembly begins at 8:00 AM for a smooth start to the race day with all necessary amenities available on-site. Free shuttle buses will transport participants between Oido Station and Siheung City Hall, making it convenient for those traveling from afar. This event promises an engaging atmosphere filled with competitive spirit and camaraderie among runners of varying abilities. With its scenic backdrop and well-organized logistics, the race offers a memorable experience that celebrates athletic achievement in one of Korea's most progressive cities.
