Moreno was due to compete in the
Women's road race at the
2008 Summer Olympics in
Beijing on 10 August, but did not start having been tested positive for
EPO.[2] Moreno arrived in Beijing on 31 July and was immediately tested. She fled the country for Spain that same day, having suffered a
panic attack. The positive test results were announced on 11 August, making Moreno the first athlete to test positive for a banned substance at the 2008 Olympic Games.[2]
