Ethiopia's Letesenbet Gidey has smashed Sifan Hassan's 10,000 metres world record set just two days earlier on the same track in the Dutch city of Hengelo.
Gidey improved the mark by another five seconds to win the Ethiopian Trials on Tuesday.
Dutchwoman Hassan had run 29 minutes 06.82 seconds to slice almost 10 seconds off the record set by Almaz Ayana at the 2016 Olympics.
Gidey demolished Hassan's mark to finish in 29:01.03, more than a minute ahead of runner-up Tsigie Gebreselama.
Until Ayana's gold medal performance in Rio nobody had got near Chinese runner Wang Junixa's controversial 1993 record of 29:31.78 but shoe technology featuring carbon plates and thick foam insoles is enabling athletes to rip up the record books.
"I expected to run a world record," the 23-year-old Gidey, who was aided by Wavelight Technology and becomes the first woman to hold both the 5,000m and 10,000m world records since Norway's Ingrid Kristiansen from 1986-1993.
"What a special night, I am so proud that after the 5,000 metres world record I am now the 10,000 metres world record holder as well.
"In this Olympic year it is the perfect preparation (for next month's Tokyo Games)."
Gidey last year claimed the world 5,000m record.
Meanwhile, two British ultra-runners smashed the world record by covering more than 330 miles (530km) of a 4.2-mile (6.8km) course in Suffolk, England.
John Stocker took the ultimate honours as the last man standing more than three days after the race started.
The 41-year-old and Matt Blackburn, 35, were among the field of 123 for the event.
Ultra runners and mesmerised observers around the world became gripped online by the astonishing performances in a small-scale event as neither man was prepared to stop.
The world record came and went before, finally, Blackburn "rang the bell" to signal that he could go on no more and slumped into his chair having covered 333.3 miles (536.4km).
Stocker, however, still had to complete his 81st lap or, by the harsh rules of Back Yard events, there would be "no winner."
He duly did, as his 81st and final lap took him to an astonishing final distance of 337.5 miles (543km).
