Kim Seongeun

Kim Seong-Eun (Korean: 김성은; born 24 February 1989 in Seoul) is a South Korean long-distance runner who competes in marathon races. She represented her country at the 2012 Summer Olympics and the 2011 World Championships in Athletics. Her personal best for the marathon is 2:27:20 hours, set in 2013.

Career

She started out doing middle- and long-distance track as a teenager and broke the South Korean indoor record for the 3000 metres at the 2005 Asian Indoor Games, taking the silver medal behind India's O. P. Jaisha. She established herself nationally in 2006 at the age of seventeen by winning the 5000 metres national title and placing second over 1500 metres. She ran in both the 3000 m and 5000 m at the 2008 World Junior Championships in Athletics and finished 15th and tenth, respectively. She also made her debut over the half marathon that year, winning a race in Incheon in March setting a best of 73:14 at the Kagawa Marugame Half Marathon in Japan.

Kim turned away from track running from 2009 onwards and focused on road running events instead. She attempted a marathon debut at the 2009 Seoul International Marathon but failed to finish the distance. She placed tenth in the half marathon at the Summer Universiade, and then came runner-up to Lee Sun-young at the JoongAng Seoul Marathon with a time of 2:37:30 hours. She only competed in two major competitions in 2010 but performed well: she ran a personal best of 71:34 at the Kagawa Marugame Half Marathon and improved her marathon best to 2:29:27 at the Seoul International race, coming fifth.
