IRONMAN athlete Imogen Simmonds accepts a finding of no fault for her anti-doping rule violation

The International Testing Agency (ITA), appointed to independently handle the results management and intelligence & investigations of anti-doping rule violations (ADRVs) for IRONMAN, reports that Swiss triathlete Imogen Simmonds has agreed to a finding of No Fault after testing positive for SARMS LGD-4033 (ligandrol) metabolite Dihydroxy-LGD-4033.

¹A report from a WADA-accredited laboratory that, consistent with the International Standard for Laboratories, establishes in a sample the presence of a prohibited substance or its metabolites or markers or evidence of the use of a prohibited method.

²‘No Fault or Negligence’ is defined as “The Athlete or other Person’s establishing that he or she did not know or suspect, and could not reasonably have known or suspected even with the exercise of utmost caution, that he or she had Used or been administered the Prohibited Substance or Prohibited Method or otherwise violated an anti-doping rule”.

³The default period of ineligibility for an anti-doping rule violation for the presence of a non-specified prohibited substance such as ligandrol is four years, unless the athlete establishes that her ADRV is not intentional. If an athlete succeeds in proving lack of intent, the starting point of the period of ineligibility is two years. The period of ineligibility may then be subject to further potential mitigation is an athlete establishes, for instance, ‘No Fault or Negligence’.

4Athletes have the right to choose not to have their case referred to a hearing panel. In these instances, the anti-doping organisation will assess the athlete’s case file and establish the applicable consequences pursuant to the anti-doping rules and the athlete will have the right to accept the proposed consequences. If the athlete refuses the proposed consequences, the case is transferred to a hearing panel. This resolution mechanism is provided for in articles 8.1.3. of the World Aquatics anti-doping rules and 8.3 of the World Anti-Doping Code and is commonly referred to as an agreement on consequences and is deemed an IRONMAN’/ITA decision.
