Former world 400m champion has accepted findings of failed test results and waived her right to a hearing before the Commonwealth Games Federation court

Following her failed doping test at the Glasgow 2014 Commonwealth Games, Botswana sprinter Amantle Montsho has accepted the findings of her positive results and has waived her right to a hearing before the Commonwealth Games Federation court.

She has now been officially disqualified from the Glasgow Games and all her results from the event will be annulled.

The 2011 400m world champion was provisionally suspended after she failed a doping test taken following the 400m final, in which she finished fourth, at the Games on July 29.

That initial sample tested positive for the banned stimulant methylhexaneamine, while Montsho’s B sample, analysed at a laboratory in London on August 4, confirmed the A sample analysis.

The 31-year-old had until August 22 to appeal, with the Commonwealth Games Federation confirming on Friday that Montsho had informed the Federation by letter, dated Wednesday (August 20), that she accepts the finding of the test results and is waiving her right to a hearing before the Federation court.

“The Commonwealth Games Federation court has determined that Botswanan athlete, Amantle Montsho, has committed an anti-doping rule violation and has disqualified her from the Commonwealth Games in Glasgow,” read a statement from the Federation in part.

“The results of all her performances at the Games will now be nullified.”

The Federation advised how the court’s decision, together with all relevant documentation, will now be forwarded to the International Association of Athletics Federations (IAAF) for further action in accordance with WADA’s World Anti-Doping Code.

Montsho had gone to the Glasgow Games as the reigning Commonwealth champion, the sprinter having won 400m gold in a Games record time in Delhi in 2010. She won the world title in 2011 and two years later was pipped to gold in Moscow by Britain’s Christine Ohuruogu.

The drug methylhexaneamine has been linked to supplements, causing federations such as UK Anti-Doping and Athletics Australia to release warnings to athletes in 2010. It is present in products available over the counter, including weight-loss aids and energy-boosters.

UK Anti-Doping warned: “There is a risk that supplements could contain this or other prohibited substances even if the ingredients listed on the label do not appear on the World Anti-Doping Code’s Prohibited List.”
