Canadian Natasha Yaremczuk finished 10th woman in Ireland’s leading marathon last year.

Natasha Yaremczuk has been handed a 14 months ban after failing an anti-doping test at the Dublin Marathon in 2017.

The Canadian runner, who is based in America, finished 10th woman in a time of 2:52:38 at the October event and claims the prohibited substances detected in her test were unknown ingredients in a supplement she took.

In a statement, Sports Ireland said Yaremczuk committed a violation of Article 2.1 of the Irish Anti-Doping Rules. Article 2.1 outlines “the presence of a Prohibited Substance or its Metabolites or Markers in your sample.”

In a doping control test immediately following her participation at the Dublin City Marathon, she provided a sample which tested positive for the presence of prohibited substances, 1,3-dimethylbutylamine (DMBA) and higenamine.

The 38 year-old promptly admitted the violation and engaged in a consultation process with Sport Ireland regarding the appropriate period of ineligibility.

Sports Ireland’s statement added: “In accordance with Article 7.6.4 of the Irish Anti-Doping Rules, Sport Ireland has issued this decision, which records that, the Athlete has committed a violation of Article 2.1 of the Rules, that she is subject to a 14 month period of ineligibility which expires on 29 December 2018 and Pursuant to Article 9.1 of the Rules, her result in the Dublin Marathon on 29 October 2017 is automatically Disqualified.”

The former triathlon World Cup winner also won the Reykjavik Marathon in August last year.
