2021 Boston Marathon and drug ban

Kipyokei finished first in the women's race at the 2021 Boston Marathon on 11 October 2021.
In October 2022, the Athletics Integrity Unit announced that she tested positive for triamcinolone acetonide in a test taken after her win. She was provisionally suspended both for this positive test and for tampering with the doping control process. The Boston Athletic Association announced that, pending appeal, she would be stripped of her title, and the rankings and prize money would be adjusted. On 20 December, it was announced that Diana Kipyokei had been banned for six years and stripped of her Boston Marathon title, with her results disqualified from 11 October 2021 onward.

Spelling of name

Less than three days before the 2021 Boston Marathon, Diana told race authorities that she prefers the spelling Kipyokei to Kipyogei. However, her request was made after her race bib had already been printed with Kipyogei.
