Faith Kipyegon unsure about running 5000m at Paris Olympics
Double world champion Faith Kipyegon is still undecided about doubling at the Olympic Games but her coach Patrick Sang has given a timeline on when they will make the final decision.
Chepkoech, 35, set her personal best marathon time of 2:22:38 in February at the Seville Marathon.
She had made her marathon debut in 2018 at the Nairobi Marathon, dominating the women's race with a winning time of 2:33:11.
Chepkoech's provisional suspension means she cannot participate in any competition until a final decision is reached which could result in an acquittal or a formal ban.
This is part of the AIU's crackdown on prohibited substances in athletics which has seen a rising number of Kenyan athletes penalized.

Why Letsile Tebogo has no plans to switch to the 400m anytime soon
Despite showing mastery in the one-lap race, Letsile Tebogo has explained why he will not switch to the 400m anytime soon.
Notably, former youth world champion Jackline Wambui was also provisionally suspended in February due to a violation involving 19-Norandrosterone and 19-Noretiocholanolone which are also prohibited substances.
She faces a two-year ban pending a Court of Arbitration for Sport (CAS) appeal.
Wambui's achievements include winning gold at the 2017 under-18 world championships and becoming the 2019 African junior champion.
