Aliphine has been a world class athlete since competing at the IAAF World Junior Cross Country Championships in high school for her native Kenya. She grew up in a tiny village called Posoy and was given her first pair of running shoes by two-time New York City Marathon champion Tegla Loroupe. Eventually running brought her to the United States where she studied public health science, something near and dear to her heart. She hopes to go into public health care after her competitive running days are over.

Aliphine received her U.S. citizenship in April of 2016 and promptly won the USATF 25k Championships less than a month later. She would go on to win the 2016 20k and 5k titles as well. She would then do one better in 2017, winning four USATF titles (cross country, 25k, 10k and 7 miles). That year also saw her run 1:09:58 for the half marathon in Houston and finish 15th at the IAAF World Cross Country Championships, the top U.S. finisher. She joined our team in January of 2018 and in May she won the USATF Half Marathon Championships in 1:10:03. She followed that up a week later with a win at the USATF 25k Championships. She was then second at the BOLDERBoulder 10k, the NYRR Mini 10k and the Peachtree Road Race. In early 2019, she was fourth at the USATF Cross Country Championships and won the Gasparilla Half Marathon. Then, in April, she was third at the Rotterdam Marathon in a huge personal best of 2:26:50. Her spring/summer season started well with a third place finish at the BOLDERBoulder 10k before an injury cut the rest of the season short. Despite an abbreviated fall training segment she then finished 12th at the TCS NYC Marathon in 2:28:12.

She kicked off 2020 by setting a team record for the half marathon (1:09:49) at the Aramco Houston Half Marathon. Then, on February 29, in Atlanta, Georgia, she WON the Olympic Trials Marathon in 2:27:23, becoming our team’s first Olympian. When the Games were postponed, Aliphine and her husband Tim decided to start a family and baby Zoe was born in January of 2021. She competed at the Olympics seven months later but was forced to drop out at 20k due to an injury. She did not return to competition until May 0f 2022 when she finished second at the Pittsburgh Half Marathon. She won the USATF 25k Championships two weeks later and two weeks after that took home the victory at the prestigious BOLDERBoulder 10k. Her final two races of the spring were a third place finish at the USATF 6k Championships and a fourth place finish at the Mastercard Mini 10k in a road PB of 31:08.

The fall of 2022 saw another major milestone moment in her career when she finished seventh at the TCS NYC Marathon. It was her first World Marathon Major top 10 and she ran a personal best of 2:26:18 to do it. She kicked off 2023 with a win at the USATF Half Marathon Championships, her 12th national title, in a PB of 1:09:37. In April, she lowered her marathon personal best once again, finishing 11th at Boston in 2:24:37. A hamstring injury in 2023 forced her to withdraw from the 2023 Chicago Marathon and to pull out of the 2024 U.S. Olympic Marathon Trials before reaching the 10-mile mark.

A graduate of Wichita State University, Aliphine was a 14-time All American, earning runner-up honors twice over 10,000 meters at the NCAA Championships. She still holds multiple school records including the outdoor 5,000 meters (15:18.86) and 10,000 (32:07.20).
