New Zealand's two-time Olympic champion Valerie Adams says she's not wasting her time thinking about her rival Nadzeya Ostapchuk.
The Belarussian has been told by the IOC to return her Olympic gold medal after failing a drugs test in London.
Two urine samples taken from the Belarussian before and after her win last Tuesday tested positive for metenolone, an anabolic steroid.
Adams admits to still being in a state of shock following her promotion to gold and isn't concerned about Ostapchuk.
Adams says as far as she is concerned Ostapchuk is history.
Little time for the 27-year-old Adams to celebrate, she competes in Stockholm later this week.
Adams says she's happy the drugs testing programme works.
