He began running competitively at Wakefield High School of Arlington, Virginia, after which he competed for a noted generation of the Arkansas track team.
At Arkansas, Iman competed in the 800, the men's distance medley relay, and occasionally would race the mile indoors.
At the 2005 NCAA DI Indoor T&F Championships, Iman ran UA's 800-meter leg in the men's distance medley race and had a lead over the entire field[5] before handing it off to 1600-meter anchorman Said Ahmed.
Ahmed was involved in a controversial finish when the meet judge claimed there was contact between him and Nathan Brannen of Michigan and subsequently gave the Arkansas men's distance medley team a disqualification mark.
