Griffith attended the California State University at Northridge, and was on the track team coached by Bob Kersee. This team, which included Brown and Jeanette Bolden, won the national championship during Griffith's first year of college. However, Griffith had to drop out to support her family, taking a job as a bank teller. Kersee found financial aid for her and she returned to college in 1980, this time at University of California at Los Angeles (UCLA) where Kersee was working as a coach. Brown, Bolden, and Griffith qualified for the 100-meter final at the trials for the 1980 Summer Olympics (with Brown winning and Griffith finishing last in the final). Griffith also ran the 200 meters, narrowly finishing fourth, a foot out of a qualifying position. However, the U.S. Government had already decided to boycott those Olympic Games mooting those results. In 1983, Griffith graduated from UCLA with her bachelor's degree in psychology. Olympic runner Griffith finished fourth in the 200-meter sprint at the first World Championship in Athletics in 1983. In the next year, she qualified for the Olympics in the 200-meter distance with the second fastest time at the United States Olympic Trials, held in Los Angeles. Evelyn Ashford, another UCLA alumna and early favorite to medal, dropped out of the 200-meter due to injury. Griffith went on to win a silver medal in the 1984 Summer Olympics. After the 1984 Olympic Games, she spent less time running. Griffith continued to run part-time, winning the 100-meter IAAF Grand Prix Final with the time of 11.00 seconds. She did not compete at the 1985 U.S. National Championship. That same year, she returned to working at a bank and styled hair and nails in her spare time. She married Al Joyner, the Olympic triple jump champion of 1984, in 1987. She returned to athletics in April 1987. Four months later, at the 1987 World Championships in Rome, Griffith Joyner finished second in the 200-meter sprint. Her success during the 1987 season resulted in being ranked second in Track and Field News' 1987 world rankings. The 200 meters remained a stronger event for her than the 100 meters, where she was ranked seventh in the United States. Before the 1988 U.S. Olympic Trials, Griffith Joyner continued to work with her coach, and now husband's brother-in-law, Kersee, two days a week, but with her new husband coaching her three days a week.
