The previous record had been set just six weeks ago by Joshua Cheptegei, who’s feat also came in Valencia but on a different course.
Kipruto also bettered the 5km road world record by reaching the halfway mark of the World Athletics Gold Label event in 13:18.
Benard Kimeli grabbed second place in Valencia to make it a one-two for Kenya, coming second in 27:12 ahead of Switzerland’s Julien Wanders who finished third in a new European record of 27:13.
Another Kenyan, Sheila Chepkirui, won the women’s race in a time of 29:46, making her the second fastest woman ever.
Rosemary Wanjiru and Norah Jeruto clocked identical times of 29:51 to finish behind Chepkirui and move to joint third on the world all-time list.
