Awards The top three men and women in both the half marathon and 10 km receive trophies and Jeongseon specialty products. Official results are provided by net time, while awards are determined by gun time. Award details may change for operational reasons.

Participant Information Half-marathon entrants must be healthy and at least 18 years old. The 10 km and 5 km races have no general age restriction, but entrants under 14 need parental consent. Participants aged 65 or older must receive a health check from a medical institution before racing. Running under another person's entry, using another runner's timing chip, failing to wear a race bib, or leaving the designated course will result in disqualification. Road controls are lifted after the time limit, so runners must follow instructions to board the sweep vehicle when required.
