Jepchirchir broke from the lead pack as they were approaching the 25-mile mark to win by 16 seconds and claim Kenya’s second consecutive gold medal in the event.
That victory set her up to claim a share of the AbbottWMM Series XIII, which she duly did by winning the 2021 TCS New York City Marathon to draw level on 50 points with Joyciline Jepkosgei.
Jepchirchir is a two-time world champion in the half marathon, having won gold at the 2016 and 2020 World Athletics Championships. In 2020 she joined the legendary trio of Tegla Loroupe, Paula Radcliffe, and Lornah Kiplagat as the only women to win more than one half marathon world title.
Her personal-best time of 2:17:16 came at the 2020 Valencia Marathon and is the fifth-fastest marathon by a woman in history.
Despite having been the youngest and least experienced of the Kenyan team at 2016 World Athletics Half Marathon Championships, she emerged as the world champion, leading a Kenyan podium sweep. The following year, she beat Keitany by seven seconds to break the half marathon world record in 1:05:06 in Ras Al Khaimah, UAE.
What made her run all the more astonishing was that she was a few weeks pregnant at the time; she gave birth to her daughter, Natalia, in October 2017. Thirteen months after giving birth she returned to racing and won the Lisbon Half Marathon and finished sixth at the Ras Al Khaimah Half Marathon.
When most of the AbbottWMM marathons were cancelled in 2020, Jepchirchir set her sights on the World Half Marathon Championships. She broke the women-only world record with a 1:05:34 run to win the Prague 21.1km—a clear sign she had returned to form—and then went on to win the world title, carving another 18 seconds off her record.
