Rita Jeptoo, Kenyan runner
Rita Jeptoo (born 15 February 1981) is a Kenyan marathon runner. Originally a winner of the Boston Marathon three times, including setting the then course record at 2:18:57 in 2014, she had also won marathons in Chicago, Stockholm, and Milan, as well as having represented Kenya in the event at the 2007 World Championships in Athletics. She was the bronze medalist at the 2006 IAAF World Road Running Championships.

Jeptoo tested positive for EPO in an out-of-competition test 25 September 2014. Athletics Kenya handed her a two-year ban from sports for the anti-doping rule violation. On 26 October 2016, the Court of Arbitration for Sport upheld an appeal from the IAAF against the leniency of the two-year ban given by Athletics Kenya, and instead set a four-year ban, and the annulling of all results from 17 April 2014, including her wins in the 2014 Boston and Chicago marathons, citing "her deceptive and obstructive conduct throughout the proceedings" as aggravating factors justifying the maximum penalty
