Kenya’s Diana Kipyokei and Purity Rionoripo have been banned for six and five years, respectively, for using prohibited substances, the Athletics Integrity United (AIU) said on Tuesday.
Kipyokei’s results have been disqualified since and including 11 October 2021. She has been disqualified as the 2021 Boston Marathon women’s winner as a result.
Their compatriot Betty Wilson Lempus has been charged with the presence of banned substance triamcinolone acetonide, the AIU said.
The Boston Athletic Association said in a statement that Kenya’s Edna Kiplagat has been elevated to women’s open division champion of the 2021 race and is now recognized as a two-time Boston winner (2017 and 2021).
Kipyokei, 28, is the second Kenyan winner of the Boston Marathon to be stripped of her title in the last decade after Rita Jeptoo also had her 2014 win revoked for a failed drugs test.
