The winner of this year's women's Beach to Beacon race has had her medal revoked after admitting to violating anti-doping rules.
The Athletics Integrity Unit, part of an international sports governing body, found that Faith Chepkoech, of Kenya, registered a positive test for a banned substance, stemming from a screening conducted shortly before participating in the 10k road race in Cape Elizabeth in August.
Race organization president David Backer said it was the first such incident in Beach to Beacon's history, and underscores the importance of testing requirements.
"We are doing the right thing by participating in doping programs to reveal, at least to the extent possible, athletes who are cheating," Backer said.
Backer said this oversight is crucial to creating a level playing field for athletes who are not using banned substances.
The race results have been adjusted to reflect a new women's overall winner: Edna Kiplagat, also of Kenya.
