Dutch break short track speed skating world records
Lashinda Demus has been upgraded from 2012 Olympic 400m hurdles runner-up to champion by World Athletics. The original winner Natalya Antyukh of Russia did not appeal her recent retroactive disqualification for doping. Antysh was already serving a four-year doping ban. Demu is the first U.S. woman to win an Olympic gold medal in the 400 m hurdles. Russia won eight track and field gold medals at the 2012 Olympics. Now it's down to one. Anna Chicherova was stripped of her 2008 Olympic bronze medal for dope.
