Kim is from
Sariwon,
North Hwanghae Province. Kim trained at
Kumchon County Juvenile Sports School. The sisters then moved to the capital
Pyongyang. Kim's standing of 8th at the
2013 World Championships in Athletics brought her fame in her just second ever race abroad. Kim then took a surprise victory over many East African favorites at the 2015
Hong Kong Marathon serving as that year's
Asian Marathon Championship, taking home a $65,000 prize. Sports journalist Pat Butcher considered the victory an important step toward the
2015 World Championships in Athletics, saying: "This is a huge win for North Korea. The last time a woman from North Korea won the world championships was in 1999 in Seville. Maybe this could be Kim's year". Kim started in the
women's marathon at the 2015 World Championships in Athletics in Beijing, China, but did not finish the race. ==Achievements==
