Brigid Kosgei: Dominating the Marathon World


Brigid Jepchirchir Kosgei, born on February 20, 1994, is a Kenyan long-distance runner who has left an indelible mark on the world of marathon running. With a series of remarkable achievements and world records, she has firmly established herself as one of the most prominent athletes in the sport.

Early Life and Entry into Running

Hailing from Elgeyo-Marakwet County, Kenya, Brigid Kosgei grew up in a modest family with six siblings. Her journey into the world of professional running began at the age of 17 when she started training alongside her boyfriend, Matthew Kosgei, who would later become her husband.

Early Career Success

Kosgei’s early career was marked by impressive performances. In the 2016 Lisbon Marathon, she secured second place, setting a personal best time of 2 hours, 24 minutes, and 45 seconds. This time was not only faster than her previous records but also exceeded the course record.

In 2017, she claimed victory at the Bogotá Half Marathon and achieved third place at the Copenhagen Half Marathon. Later that year, at the 2017 Chicago Marathon, Kosgei stunned the world with a personal best time of 2 hours, 20 minutes, and 22 seconds, marking the sixth-fastest time ever recorded at the Chicago Marathon. Her talent was further demonstrated when she shattered the course record at the Honolulu Marathon just weeks after her Chicago success.

Emergence as a Marathon Star

The year 2018 was pivotal for Brigid Kosgei. Although she finished second in the London Marathon, she seized victory at the Chicago Marathon, breaking away from the competition and setting a new personal best time of 2 hours, 18 minutes, and 35 seconds.

London Marathon Triumph

Kosgei’s ascent continued in 2019 when she became the youngest woman to win the prestigious London Marathon. Her finishing time was the third-best ever recorded in London, following Paula Radcliffe in 2005 and Mary Keitany in 2017.

Setting the World Ablaze

The highlight of Brigid Kosgei’s career came in October 2019 during the Chicago Marathon. She not only clinched victory but also rewrote history by setting a remarkable world record time of 2 hours, 14 minutes, and 4 seconds. This achievement was a testament to her incredible talent and unwavering determination. She finished over six minutes ahead of her closest competitor, Ababel Yeshaneh.

Kosgei’s world-record-breaking performance sparked discussions about the role of specialized Nike shoes, which some claimed gave her an advantage of 60 to 90 seconds. Nevertheless, her feat remains an iconic moment in the sport.

Continued Success

In February 2020, Brigid Kosgei participated in the Ras Al Khaimah Half Marathon, where she finished second to Yeshaneh, but her time was two seconds better than the previous world record. She further demonstrated her prowess by setting a new record for the 10-kilometer mark during the race.

Later that year, she claimed another victory at the London Marathon, leading the pack and finishing over three minutes ahead of her competitors with a time of 2 hours, 18 minutes, and 58 seconds.

Olympic Dream

Kosgei was selected to lead the Kenyan women’s marathon team for the 2020 Summer Olympics in Tokyo, alongside Vivian Cheruiyot and Ruth Chepng’etich. She made her Olympic debut, finishing second behind Peres Jepchirchir.
