Allyson Felix was denied a golden goodbye at the World Championships after the United States took bronze behind Dominican Republic and Netherlands in a spectacular 4x400m mixed relay in Eugene, Oregon on Friday.
The home crowd had roared with delight as seven-times Olympic gold medallist Felix took the baton for the second leg though the 36-year-old, running in her final major championship race, appeared to tire down the stretch after a strong start.
The United States still managed to open a massive gap at the final changeover and looked well set for victory before the Dominican anchor leg reeled in on the American Kennedy Simon down the home stretch, to win gold and improve on their Tokyo silver.
