At age twenty she finished the Daegu Marathon in tenth place with a time of 2:48:57 hours. Later that year she was runner-up in the event at the Korean National Sports Festival. In the 2014 season she set a half marathon best of 77:13 minutes to finish runner-up in Incheon. She ran two marathons within the space of a week in November, placing sixth at the National Games then winning her first major race, with 2:37:47 hours to top the podium at the JoongAng Seoul Marathon.[https://more.arrs.run/runner/29883 Ahn Seul-Ki].
