2027 Seoul Marathon Participant Instructions

■ Consideration of Participants’ Health Conditions

Serious safety incidents, including injuries, exhaustion, cardiac arrest, and other medical emergencies, may occur during the Seoul Marathon.

Participants must carefully consider their own health conditions before deciding whether to take part in the race.

Participants with underlying conditions such as heart disease, hypertension, diabetes, or respiratory disease, or those who have recently experienced any health problems, must decide whether to participate only after confirming, through a medical institution or other appropriate means, that they are able to run without undue risk.

If a participant feels any physical abnormality during the race, the participant must immediately stop running and seek assistance from the nearest event staff member or medical personnel.

The Organizer will operate ambulances and a medical support system at major points along the course; however, each participant must check his or her own health condition and participate responsibly.

■ Insurance Coverage

The 2027 Seoul Marathon will be covered by commercial general liability insurance for event operations.

However, compensation for injuries or accidents occurring during the race will be available only within the terms, conditions, and coverage limits of the insurance policy in effect. The Organizer’s liability may be limited for any damages exceeding the scope of insurance coverage or for accidents caused by the participant’s intentional misconduct or negligence.

For insurance-related inquiries, please contact the Secretariat.

■ Registration and Eligibility

All information entered at the time of registration, including name, date of birth, and contact details, must be accurate and based on fact.

If false information, use of another person’s information, or failure to meet eligibility requirements is confirmed, the registration may be cancelled or participation may be restricted, and any resulting disadvantage shall be borne by the applicant.

* Full Course: Healthy men and women aged 18 or older who agree to the Participant Instructions and submit an officially recognized race record certificate (a certificate showing completion of a full marathon within 4 hours 59 minutes 59 seconds at a race held between January 1, 2024 and May 10, 2026).

* 10km Course: Healthy men and women who agree to the Participant Instructions.
    (Record submission is for group assignment; participants who do not submit a record will be assigned to a rear group.)

※ Participants may not take part using assistive equipment, including wheelchairs, inline skates, or similar devices.

※ Participants may not take part accompanied by infants or baby strollers. Athletes who, as of the race date, are currently registered in athletics (running events), triathlon, or modern pentathlon may participate, but are excluded from awards. Former athletes whose registration has been cancelled for less than two years, or those who have participated in the National Sports Festival as a city or provincial representative, are also excluded from awards. If such fact is confirmed after the race, any prize-winning result will be cancelled and the prize must be returned. Group registration is not permitted; only individual registration is available.

■ Prohibition on Transfer of Entry Rights and Unauthorized Participation

Registration under an assumed or borrowed name, transfer, sale, lending of an entry right after registration, and participation by a substitute runner are not permitted.

If the actual participant differs from the registered applicant, the participant may not receive compensation for any accident occurring during the race. If participation under a borrowed name or transfer of an entry right is discovered, the participant may be subject to disadvantages, including restrictions on future participation.

If conduct that interferes with event operations is confirmed, including organized or commercial transfer or sale of entry rights or fraudulent use of a timing chip, the Organizer may take any measures deemed necessary by the Secretariat, including cancellation of participation, invalidation of records, restriction of future participation, and legal proceedings.

For the full course of the 2027 Seoul Marathon, starting groups will be determined based on the distribution of finisher records from the 2026 Seoul Marathon.

Group S will be assigned to Hall of Fame inductees who achieved a sub-3 record in the 2024 or 2025 Seoul, Gongju, or Gyeongju Marathon, or in the 2026 Seoul Marathon. Other Hall of Fame members will be assigned to groups according to the full-course record they submit.

10km: Scheduled to start in group order beginning with Group A.

Records will be measured by net time, starting from the moment the participant crosses the timing mat at the start line.

For the safety of participants, please follow the instructions of event staff and start in an orderly manner with sufficient spacing.

Participants must start from their assigned group. Participants who leave their bib-number group and start from a forward group will be disqualified. Moving to a group behind one’s assigned group is permitted.

Parking is not available at the race start venues, Gwanghwamun Square and Jamsil Sports Complex. Please use public transportation.

■ Course Time Limits

As the race passes through downtown Seoul, the time limits will be strictly enforced in order to minimize inconvenience to citizens: 5 hours for the full course and 1 hour 30 minutes for the 10km course.

After the time limit for each distance has passed, traffic control will be lifted. Participants are requested to cooperate so that they can finish within the permitted time and must follow the instructions of race officials.

The Organizer shall not be responsible for any accidents occurring on the road after the lifting of traffic control, or for any fault attributable to participants.

■ Changing Rooms and Baggage Storage

Changing rooms and baggage storage areas will be operated on race day for the convenience of participants.

Baggage storage areas are separated by participation division, and participants must deposit their belongings at the designated storage area.

After finishing the race, participants may retrieve their belongings by presenting the sticker issued at the time of baggage check-in.

Valuables will not be accepted for storage, and the Organizer cannot check the contents of stored items in advance; therefore, the Organizer shall not be responsible for any loss.

As theft of cash and valuables may occur at the venue, participants are advised not to carry cash or valuables other than items necessary on race day.

■ Beverages and Refreshments

Water and sports drinks will be provided at every 5km point and at the finish area, and sponges will be available every 5km after the 7.5km point.

Refreshments for nutritional replenishment will be provided at the 20km and 30km points. (Items provided and locations are subject to change.)

■ Instructions on Use of the Timing Chip

Records will be measured by net time, starting from the moment the participant crosses the timing mat at the start line.

Upon receiving the race packet by delivery, participants must immediately check whether the bib and timing chip have been properly included. If there is any issue, participants must contact the Secretariat. (02-312-1998)

The timing chip is attached to the back of the bib. If the chip is bent or removed, the record may not be measured properly.

The bib must be worn on the front outer layer of clothing so that it is clearly visible. The chip is disposable and does not need to be returned. Participants who do not attach their bib (chip), or who do not pass through the timing mats at the start, finish, and along the course, will not have their records measured and will be disqualified.

Participants are fully responsible for any loss or damage to a bib that has been properly delivered. Bibs cannot be reprinted, and the Secretariat will not issue spare bibs.

<Precautions Regarding the Timing Chip>

1. Do not bend or remove the timing chip.

2. Records will be measured only when the bib with the chip attached is worn properly.

   (Please make sure to wear the bib on the front outer layer of clothing so that it is clearly visible.)

3. The chip is disposable and does not need to be returned.

※ Participants who do not attach their bib (chip), or who do not pass through the timing mats at the start, finish, and along the course, will not have their records measured and will be disqualified.

4. If you run while carrying a communication device, please keep it in a position that does not overlap with your bib number.

5. If a communication device is positioned directly behind the bib number, communication interference may occur and the record may not be measured.

6. Problems may also occur if a smartwatch is in the same line as the chip at a timing measurement point.

7. Moisture, such as energy gels, may also interfere with communication.

8. A foil blanket may block communication and prevent the record from being measured.

■ Disqualification

After payment has been completed and participation has been confirmed, transfer of eligibility and substitute participation will not be recognized.

Changing participants or participating as a substitute runner will result in disqualification, and no record certificate will be issued.

Running with another person’s chip, committing fraudulent acts that interfere with record determination, failing to wear a bib, altering a bib, or attaching a bib that has been modified without authorization will also result in the record not being recognized, and participation may be stopped by event operations staff. Please note that such acts may also result in disadvantages, including restrictions on participation for the next five years, or legal action.

■ Cancellation of Participation and Refunds

Cancellation of participation is available until 2:00 p.m. on Monday, November 30, 2026. After that time, cancellation and refunds will not be available.

Card Cancellation: For card payments, approval will be cancelled after identity verification. Depending on the card company, cancellation and refund may take 3 to 7 business days.

How to Cancel Participation: A refund request may be made through the personal verification process after contacting the Secretariat (via Dongma Club Inquiry).

The Organizer may provide important information related to event operations through text messages, email, website notices, and other means. Participants must accurately enter their contact details and email address.

Any disadvantage arising from failure to receive notices due to incorrect contact information or failure to reflect changed contact information shall be borne by the participant.

■ Provided Items

For domestic participants, bibs and commemorative items will be sent by delivery before the race to the address entered at the time of registration, and the delivery cost will be borne by the Organizer.

Overseas participants must collect their participant items (bib and commemorative items) from the information booth on race day.

Finisher medals will be provided on site only to finishers.

■ Protection and Use of Personal Information

The Seoul Marathon collects information that can identify individuals, including the applicant’s name, date of birth, address, contact information, and email address.

The collected personal information will be used within the scope necessary for event operations, including insurance enrollment, participant verification, event operation notices, provision of records, and response to inquiries. Personal information may be shared with sponsors and partners in order to provide better services. Personal information will not be disclosed to other individuals, companies, or institutions for any other commercial purpose.

However, personal information may be disclosed in order to take legal action if an applicant violates these instructions or the Terms of Use, causes legal harm to another person, or engages in conduct contrary to public morals and social order.

■ Photography, Filming, and Use of Portrait Rights

At the event venue, photographs and videos of participants may be taken for purposes including records, news reporting, publicity, and event operations.

By participating in the race, participants are deemed to consent to the Organizer’s use of their photographs, videos, records, and related materials taken by the Organizer on the event website, social media, printed materials, promotional materials, press releases, and other media within the scope of event promotion and public-interest purposes.

■ Other Matters

The Organizer has the authority to revoke eligibility, invite special guests, suspend or cancel the race, change the course, and take other necessary measures.

The race may be cancelled or changed due to force majeure events beyond the control of the Organizer, including natural disasters, the spread of infectious diseases, administrative measures by the government or local authorities, traffic control, social disasters, or other similar circumstances.

In such cases, refunds, the method of event operation, and detailed measures will be announced separately in accordance with the Organizer’s policy.

All other matters shall be governed by the latest competition rules of the Korea Association of Athletics Federations and the interpretation of the Organizer.
