The 25-year-old ran the event in two hours, 14 minutes and 4 seconds, easily inside Paula Radcliffe’s time of 2:15:25 at the London Marathon in 2003.
However, despite putting almost 7 minutes between herself and her competition, Brigid is convinced she can do even better next race.

“I think 2:10 is possible for a lady,” she told The Guardian. “I am focused on reducing my time again.”
Kosgei (whose time would have been a world record for both genders back in 1964) was beaten by just 22 competitors in the men’s race.
“I was not expecting this,” she said, shortly after crossing the finishing line. “But I felt my body was moving, moving, moving so I went for it. This is amazing for me.”
Brigid wasn't the only athlete to accomplish an incredible feat over the past few days: on Saturday, Eliud Kipchoge became the first marathon runner ever to clock a sub-2 hour time. The Olympic champion and fellow Kenyan marked 1 hour, 59 minutes and 40.2 seconds at the INEOS 1:59 Challenge - an assisted event that unfortunately, doesn’t count as a world record.
Former US President Barak Obama took to Twitter over the weekend to congratulate the pair.
"Yesterday, marathoner Eliud Kipchoge became the first ever to break two hours," he wrote. "Today in Chicago, Brigid Kosgei set a new women's world record. Staggering achievements on their own, they're also remarkable examples of humanity's ability to endure—and keep raising the bar."
