Triathlete receives sanction

29 August 2019

The Australian Sports Anti-Doping Authority (ASADA) today acknowledged the decision of International Triathlon Union (ITU) Anti-Doping Hearing Panel to impose a four-year ban on athlete Stephen Thompson for the presence of a prohibited substance.

On 13 September 2018 during the 2018 ITU World Triathlon on the Gold Coast, Mr Thompson provided a urine sample which returned an Adverse Analytical Finding (AAF) for the Prohibited Substance recombinant Erythropoietin (rEPO).

Recombinant erythropoietin (rEPO) stimulates the production of red blood cells and improves an athlete’s aerobic capacity by increasing the body’s ability to deliver oxygen to muscles.

Side effects include thickening of the blood which can cause blood clotting (thrombosis) which can lead to heart attack and stroke. The use of rEPO can also lead to seizures.

The ITU Anti-Doping Hearing Panel imposed a four-year ban on Mr Thompson commencing on 19 December 2018 and all results from 13 September 2018 onwards have been disqualified.

Mr Thompson is ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 19 December 2022.
