Additional event notes
The short answer
The 2026 JTBC Seoul Marathon is Sunday, November 1. The organizer lists the full-marathon start at Sangam World Cup Park and the finish at Olympic Park; the 10K finishes at Yeouido Park. The full marathon is for runners age 18 or older who can finish within five hours.
Domestic entry is handled through Runable. The official English registration page says its remaining international allocation is for foreign participants who live outside Korea. Confirm which entry channel applies before paying.

Expo and bib pickup
The current English pre-race page lists the Korea Running Expo at SETEC from October 29 to October 31, 2026. It says:
- participants must collect their own bib;
- race-day bib collection is unavailable;
- proxy pickup is unavailable;
- a passport or government photo ID is required;
- the bib-number email should be shown digitally or on paper.
Do not plan a same-day arrival. Leave enough travel buffer to reach SETEC during the published pickup window and recheck the final participant email.
Train for the course, not a generic flat marathon
The organizer describes a point-to-point route across Seoul, from the World Cup area toward Olympic Park. A practical preparation block should include:
- steady long runs without late pace collapse;
- marathon-effort work placed inside—not after—an appropriate long run;
- fueling while moving at goal effort;
- turns and mild terrain changes without pace surges;
- an early-morning routine that matches race logistics.
Use the marathon training hub to choose a plan by current base and the running pace calculator to model ranges. A five-hour event limit is an operational rule, not evidence that a particular goal pace is safe or realistic for you.
A simple race-day pacing card
- First 5K: settle below the urge to race the crowd.
- Middle kilometres: hold effort through turns, small grades, and congestion.
- Fueling: use the exact products and timing rehearsed in long runs.
- Final 10K: increase only if breathing, form, and fueling remain controlled.
Stay with the official route and assigned start procedures rather than following another runner through a wrong access point.
Registration and travel checklist
- Confirm the correct domestic or international entry channel.
- Save proof of entry and the organizer emails.
- Book expo access before race-morning transport.
- Bring the required photo ID to SETEC.
- Confirm the final start wave and bag-drop rules.
- Download or screenshot the latest course and event instructions.
- Recheck weather and public-transport changes during race week.
What remains provisional
The organizer warns that locations and operating details can change. Treat exact wave times, aid-station products, baggage procedures, and the final course map as race-week facts. Directory pages do not override the organizer.
