18th Cyber Territory Defense Marathon

The 18th Cyber Territory Defense Marathon is a running event held at the Mulbit Stage in Yeouido Hangang Park. The race starts at 8:00 a.m., and participants gather at 7:00 a.m.

There are three race options: 5 km, 10 km, and Half. Entries are limited to the first 1,000 runners for the 5 km, 1,500 for the 10 km, and 500 for the Half, so each category may close early.

The 5 km race costs 35,000 KRW and includes a performance T-shirt, and no timing chip is used. The 10 km and Half races cost 50,000 KRW each, and timing chips are used for both.

Registration runs from June 17, 2026, to 1:00 p.m. on August 3, 2026. Groups of 40 or more receive a 10% discount and a booth/banner benefit, and race packets are shipped by courier about one week before the event.

Refunds are available until 1:00 p.m. on August 12, 2026. After that deadline, applications, changes, cancellations, and refunds are not allowed. If the event is suspended due to natural disasters or force majeure, the entry fee will not be refunded, so please check your schedule before registering.
