(CNN)Peres Jepchirchir broke her own world record in the women's half marathon, crossing the line in one hour, five minutes and 16 seconds to win gold at the World Athletics Half Marathon Championships in Gdynia, Poland.

The 27-year-old Kenyan beat her previous best by 18 seconds, set in Prague on September 5, narrowly edging out Germany's Melat Kejeta by just two seconds. Yalemzerf Yehualaw of Ethiopia was just a further second back to take bronze in an extraordinarily close race.

It was Jepchirchir's second half marathon world title, having previously claimed gold in 2016.
