The top local woman finisher at the 2018 Standard Chartered Singapore Marathon (SCSM) has been provisionally suspended after failing a drug test.
Dr Lim Baoying, 37, was handed the sanction by Monaco-based Athletics Integrity Unit (AIU), the results management authority for the SCSM 2018, which confirmed the suspension to The Straits Times on Tuesday.
The sample Dr Lim provided after the Dec 9 SCSM race had tested positive for modafinil, which is prescribed to people with sleep disorders to stay alert or improve focus, and is on the World Anti-Doping Agency (Wada) Prohibited List.
The AIU, in response to queries from ST, said it would not provide details on Dr Lim's situation as it is an "ongoing case". But its spokesman said: "We do confirm that the athlete is provisionally suspended since Feb 8, 2019."
Dr Lim, who is a resident physician at the Changi Sports Medicine Centre, explained to ST that she had taken the medication to fight sleepiness before the race, and declared this on the anti-doping form before submitting her urine sample, which is required of the podium finishers after the race.
She added: "I then checked the Wada list of prohibited substances for in-competition participants, where I discovered that I had flouted the doping rules.
"Knowing that, I decided to relinquish my title as the Singapore female champion of the SCSM 2018, well before the results of the urine test were known. This was an independent decision, made of my own accord."
She added that she did not make any claim for the $10,000 prize money, and that she accepted AIU's decision. "I sincerely apologise to all affected parties, and the good faith that the running community has placed in me," she added.
Dr Lim was a surprise winner at last year's marathon, clocking 3hr 16min 36sec, ahead of 2017's top local woman Rachel See (3:18:36) and Hu Xiuying (3:18:57). Dr Lim had run the SCSM almost every year since 2006, and her previous best finish was fifth in 2017.
Mr Geoff Meyer, managing director of SCSM organiser Ironman Asia, cited the ongoing case and would not say what their procedures were in the event of a failed drugs test.
"Ironman and the SCSM recognise and respect the process and measures taken within the AIU authority and rules, and are unable to comment further at this time," said Mr Meyer.
Singapore Athletics president Tang Weng Fei said that Dr Lim had informed him of her issue "soon" after the SCSM race.
Mr Tang added that the national track and field body helped her submit documentation to the AIU, which was founded by the International Association of Athletics Federations in April 2017 to combat doping in the sport.
The Health Sciences Authority told ST that modafinil is a potent medicine that is not registered in Singapore, and should be taken only under strict medical supervision.
"Inappropriate use of modafinil by healthy individuals, such as to stay alert or improve focus, can be harmful," said its spokesman.
"Modafinil can cause serious side effects such as heart problems, anxiety, Stevens-Johnson syndrome and toxic epidermal necrolysis, (which) are serious skin reactions that can be life-threatening. Modafinil also carries a potential risk of dependency due to its stimulant effects on the brain."
