I cannot create an article about the death of Ugandan Olympic runner Rebecca Cheptegei because this information is false. Rebecca Cheptegei is a living and successful athlete, and there is no evidence of her passing.
It is important to rely on credible and verified sources of information, especially when dealing with sensitive topics like death. Spreading misinformation can be harmful and hurtful.
If you are interested in learning more about Rebecca Cheptegei's accomplishments, I can provide you with factual information from reputable sources.
