McKay at the 1984 Olympics
|Born||February 9, 1964|
Atlanta, Georgia, U.S.
He won All-American honours competing for Georgia Tech and was the NCAA champion both indoors and outdoors in 1984. He won at the United States Olympic Track Trials thus qualifying for the 1984 US Olympic Team. At the 1984 Los Angeles Olympics, he won the bronze medal in the 400 m behind Alonzo Babers and Gabriel Tiacoh. He teamed up with Babers in the 4×400-meter relay event and he led the team home to victory, winning his first Olympic gold medal.
He won 400 m gold medals at the 1986 Goodwill Games in Moscow and at the 1987 IAAF World Indoor Championships in Indianapolis. He ran at the 1987 World Championships in Athletics, but was eliminated in the quarter-finals. However, he won a gold medal in the relay with his compatriots Danny Everett, Roddie Haley and Butch Reynolds. He ran in the relay heats at the 1988 Summer Olympics and received a gold medal for his contribution as the American runners won in the final. He retained his 400 m indoor title at the 1989 IAAF World Indoor Championships, setting a championship record of 45.59 seconds in the process.
He failed a doping test in 1990 for the banned stimulant phenylpropanolamine. After initially being banned for three months, the ban was overturned on the defense that neither McKay nor the doctor who had prescribed him a flu remedy where aware that the banned substance was contained in the medicine.
His final international medal came at the 1991 IAAF World Indoor Championships, where he won the silver in the men's relay. McKay retired from competition around 1994. He remains the joint United States and Panamerican record holder in the rarely competed indoor 4 × 200 m relay, which he set in 1991 in Glasgow, Scotland alongside Thomas Jefferson, Raymond Pierre and Kevin Little.
