Darden had a very successful track career for his high school, Norristown High, Pennsylvania; for his university, Arizona State; and for his track club, Philadelphia Pioneers. At high school, Darden won multiple state championships and achieved national fame by recording national indoor records at 300 and 500 yards. At Arizona State University, Darden was a key member of the track team, competing in the sprints and sprint relay, and helped the team to their first NCAA Championship in 1977. Also in 1977, Darden was a member of two Arizona State record-breaking relay teams. The first tied the 4x220 yards world best with a time of 1:21.7 in Austin, Texas on April 1 at the Texas Relays. The second broke the world record for the 4×200 metres with a time of 1:21.4 in Philadelphia, Pennsylvania on April 30 at the Penn Relays. In 1979, Darden having finished second at the USA championships qualified for the Pan American Games. Willie Smith, as American No. 1, was expected to be the main rival to the legendary Cuban athlete Alberto Juantorena. In the end a foot injury and a problem with a shoe put paid to his chances, and it was an inspired piece of running by Darden that meant it was he who was to beat Juantorena into second. Darden finished third in 400 m at the 1979 Athletics World Cup and anchored the United States 4 × 400 m relay team to victory. Darden received some criticism for his run in the individual event but ran a superb relay leg to redeem his reputation. At the 1981 Athletics World Cup, Darden again anchored the United States 4 × 400 mrelay team to victory, in a time that was then the third fastest ever. Darden never ran in an Olympics. As a high-school student he reached the quarter finals at the United States Olympic Trials in 1976. In 1980 though he finished fifth and so qualified for the 4 × 400 m relay squad but the United States boycotted the 1980 Olympics. Darden set his personal best in the 400 metres on June 21, 1981 in Sacramento.
Darden was ranked among the best in the US and the world in the 400 m sprint from 1977 to 1982, according to the votes of the experts of Track and Field News.
