After graduation, Smith continued as an athlete. He was twice United States National Champion at 400m., in 1979 and 1980. His reward in 1979 was a place on the American team for the
Pan American Games at 400 m. Here he won bronze. Smith finished second in the 400 m. final at the
United States Olympic Trials for the
1980 Olympics. He was unable to compete due to the
United States boycott of those games. A defeat of the Olympic champion
Viktor Markin was little consolation. Years later, he did receive one of 461
Congressional Gold Medals created especially for the spurned athletes. Smith was also a member of winning United States 4 × 400 m. relay teams in the
1979 and
1981 IAAF Athletics World Cups. In 1983, he competed at the inaugural
IAAF Athletics World Championships in the American 4 × 400 m. relay team. However, he collided with a competing Soviet Union runner on the third leg, falling, leaving the American final leg runner, the great 400 m. hurdler
Ed Moses, with no chance of victory despite his valiant but vain effort to catch the leaders - the team eventually finished down the field. Smith said "It was a stupid mistake. I almost quit the sport." In 1996, Smith attempted to compete at the
1996 Atlanta Olympics as a 40-year-old. His struggle was chronicled in the
New York Times. In 1997, Smith was inducted into the Alabama Sports Hall of Fame. == Rankings ==
