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.
