Ethiopian Meselech Melkamu has become only the fourth woman in history to break the 30-minute barrier for 10,000m, clocking 29:53.80 - second fastest of all-time mark - at the Vechtse Banen in Utrecht, the Netherlands on Sunday.
Melkamu, 24, broke Tirunesh Dibaba's African and national record of 29:54.66 achieved at the 2008 Beijing Olympics in China.
She ran at World Record-pace at 4k, then slowed a bit to finish in well clear of Kiplagat.
Kenya's Florence Kiplagat finished second in a new Kenyan record of 30:11.53 with Ethiopia's Wude Ayalew coming in third in 30:11.87 to become the tenth fastest all-time woman.
The women's 10,000m world-record remains at 29:31.78 by China's Wang Junxia set in Beijing in 1993.
