### 2019

At the 20th Dubai Marathon, Chepng'etich set a new course record of 2 hours, 17 minutes and 8 seconds.
On 28 September, she won the world title in the marathon at the 2019 World Athletics Championships in Doha, Qatar, clocking 2:32:43 after a midnight start due to sweltering, humid conditions. The silver medal went to Rose Chelimo of Bahrain with a time of 2:33:46, and bronze went to Namibia's 39-year-old Helalia Johannes, who clocked 2:34:15. Chepng'etich's time was the slowest world championship-winning time in history for the women's marathon. Due to the unfavorable conditions, only 40 out of 68 starters finished the race in Doha.

On 10 October 2021, she took her first victory at a World Marathon Major by winning the 2021 Chicago Marathon with a time of 2:22:31. She went out fast in a 67:34 first half, and concluded significantly slower with a 74:57 second half, but still won by nearly two minutes.

### 2022

On 13 March, Chepng'etich clocked the second fastest ever women's only marathon time to win the Nagoya Women's Marathon in Japan, a World Athletics Elite Platinum Label race. In a new course record, she ran a negative split 2:17:18 with a 69:03 first half and a 68:15 second half. At the time, this was the joint seventh-fastest time in history, which gave her an 87 second margin of victory. She won $250,000, the biggest official prize in professional running up to that point.
On 9 October, Chepng'etich successfully defended her Chicago title at the 2022 Chicago Marathon with a time of 2:14:18, a personal best by almost three minutes, then the second-fastest time in history, and just 14 seconds outside of compatriot Brigid Kosgei's then-world record of 2:14:04. Chepng'etich ran most of the race well under world record pace as she went out very fast with her first 10 miles clocked at 49:49. She ran the first half in 65:44 before running the second half much slower in 68:34. The win made her the first woman in history to break the 2:18 barrier on three separate occasions.
