Tyler Hamilton loses Olympic gold after admitting to doping
American cyclist Tyler Hamilton has been stripped of his 2004 Olympic gold medal after admitting that he took performance enhancers.
The 41-year-old, who snatched the top honour in the time trial in Sydney, was found guilty of doping at the time but denied the allegations and was permitted to keep his medal following a successful appeal.
Eight years later, the American cyclist has admitted that he did take a banned substance during the Olympic Games while testifying at Lance Armstrong's federal trial.
