[1] In March 2023, Aprot was banned from competition for four years by the Anti-Doping Agency of Kenya (ADAK) after metabolite of letrozole (bis-4-cyanophenyl-methanol) had been found in drug test in May 2022.

[3][4][5][6] She made her international debut at the age of sixteen, coming ninth in the junior race of the 2010 IAAF World Cross Country Championships.

The event marked a change for Aprot, who wore spikes rather than going barefoot as she previously had, but she managed a personal best of 15:17.39 minutes.

[13][14] At the 2016 Rio Olympics, Aprot came in fourth place in the women's 10,000 m. She was responsible for the extremely fast pace that helped Almaz Ayana break the world record, and Aprot set a personal best time of 29:53.51 which marked her as the fifth fastest woman of all time in the event behind the three athletes who beat her in the Olympic final and Wang Junxia of China.

At the 2017 IAAF World Cross Country Championships in Kampala, Uganda, Aprot came second to her fellow Kenyan, Irene Chepet Cheptai.
