Norfolk, Va. ? Disgraced former Olympic track standout Tim Montgomery, once dubbed “the world’s fastest man,” was sentenced Friday to five years in prison for dealing heroin to an informant.

“I was blind – I never had a job in my life,” Montgomery told U.S. District Judge Jerome B. Friedman. “I did the wrong thing.”

Montgomery, 33, will serve the five-year sentence after he completes a 46-month prison term for an unrelated conviction in New York.

Under an agreement with the government, he pleaded guilty in July to possession and distribution of more than 100 grams of heroin. He received the minimum term under federal sentencing guidelines.
