Missed Seoul Marathon registration? Daegu Marathon entries open October 12

Domestic entries for the 2027 Seoul Marathon sold out on June 4. The final chance for a Seoul spot is 2 p.m. on November 30, when cancellations close. Registration for the Daegu Marathon opens at 10 a.m. on October 12.

At 7 p.m.

on June 1, just after Group A registration opened, a novice runner posted a video to the YouTube channel casual runner jun. "I thought there would be a lottery for each group, but instead they selected runners from each group on a first-come, first-served basis."

The runner was in Group G, with a window at 9 p.m.

the following night. On June 4, after the three-day registration period had ended, the Seoul Marathon office posted a notice on Dongma Club.

It was one line: entries for the 2027 Seoul Marathon were "completely sold out." The door to the March 21, 2027 start in Gwanghwamun Square is not entirely closed.

Official cancellations are the last chance: spots may reopen until 2 p.m.

on November 30. The nearest alternative is the Daegu Marathon, which opens registration at 10 a.

m. on October 12.

1Daegu Marathon registration opens at 10 a.m. on October 12

The Daegu Marathon will be held on February 28, 2027, three weeks before Seoul. Marathon registration runs from 10 a.m.

on Monday, October 12, 2026 through October 18, with payment due October 19–25. Registration for the 10K and fun run runs from October 26 through November 1, with payment due November 2–8. The field is capped at 15,000 for the marathon, 13,000 for the 10K and 4,000 for the fun run, for a total of 32,000.

With 40,130 runners in the 2025 mass-participation field, the event is scaling back. The course is changing, too. The start and finish will move from Daegu Stadium to National Debt Repayment Movement Park, while the start time shifts one hour earlier, from 9 a.

m. to 8 a.m.

Local media reported that the course will center on Dalgubeol-daero and pass Jonggak intersection, Gamsam Station and Sinmae Station. One detail stands out: registration and payment have separate windows. Daegu city officials said unpaid entries will be combined with any remaining capacity and reopened later, with details to be announced.

Entry fees and registration procedures will appear in the race regulations. Only Daegu Marathon members can apply, so create an account before October 12.

2Hapcheon Cherry Blossom Marathon: 2026 entries closed in 49 minutes

The 26th Hapcheon Cherry Blossom Marathon will be held in Hapcheon on Sunday, March 28, one week after Seoul. The program includes a marathon, half marathon, 10K and 5K. Hapcheon County has not yet announced 2027 entry fees or registration dates.

Registration for the 25th edition in 2026 was scheduled to run from December 1, 2025, through February 28, 2026, but all distances sold out in 49 minutes, according to the county’s post-race report. Entries could not be transferred after confirmation in 2026. For the 25th edition in 2026, the marathon and half marathon each cost 40,000 won, and the marathon cutoff was 5 hours.

Those are the first numbers to check when the 2027 details are released. Seoul opened registration group by group in one-hour windows spread across three days. In Hapcheon, every distance sold out in 49 minutes.

Gunsan, South Korea

3Gunsan Saemangeum Marathon: First Sunday in April, registration in January

The Gunsan Saemangeum Marathon is held each year on the first Sunday in April, putting the expected 2027 date on April 4. That date has not yet been officially confirmed. The race starts and finishes at Wolmyeong Sports Complex.

In 2026, the marathon course ran through downtown, crossed the Geumgang Estuary Barrage and reached its turnaround near Napo Police Substation. Registration opens in early January each year and closes once the entry limit is reached. In 2026, entry fees were 60,000 won for the marathon, 40,000 won for the 10K and 25,000 won for the 5K.

For the 2026 race, marathon and 10K runners were assigned to start groups based on submitted result certificates. Marathon groups ranged from Group A for runners under 3 hours to Group E for runners under 5 hours. In 2026, marathon applicants had to be at least 18 years old and capable of finishing within 5 hours.

Roads reopened after 5 hours, and runners still on the course had to board the sweep bus.

Editor's pick

Runners who missed the Seoul Marathon should mark three dates on the calendar: 10 a.m. on October 12, when registration opens for the Daegu Marathon, held three weeks before Seoul; 2 p.

m. on November 30, the last time to check for canceled Seoul entries; and the winter announcements for registration in Hapcheon and Gunsan. Anyone targeting Seoul in 2028 can prepare around the 2027 race rules.

Submit an official marathon certificate first, pursue any available route to priority registration, then log in at the assigned group time when general registration opens. The submission window and the period for valid results are announced afresh for each race, so January 1, 2024, through May 10, 2026 applies only to the 2027 event. But the requirement for an official marathon time of 4:59:59 or faster is unlikely to change much.

Registration for the Daegu Marathon opens at 10 a.m.

on Monday, October 12.
