Crockett was a track star from his time at high school in Webster Groves in St. Louis County, Missouri. In 1968 as a senior he ran the second fastest time that year by a high-school student. He was recruited to Southern Illinois University in Carbondale, Illinois, where he competed successfully on their track team, including becoming twice USA champion in the 100 yards sprint, in 1969 and 1970.
In 1974, he ran the fastest 100-yard dash with manual timing of 9.0 seconds, a record he still holds. This was deemed at the time by the Los Angeles Times as "Immortality in 9 Seconds Flat", and he was quickly tagged with the title the world's fastest man by Track and Field News who put him on their June 1974 cover.
Crockett has gone on to become an administrator and director of business development for the College of Nursing at Forest Park Hospital in St Louis, Missouri.
After college, he moved back to Webster Groves where he had attended Brentwood and Webster Groves High School. His local community recognised his achievements by naming a park in his honour, 'Ivory Crockett Park'. As a gift to his local community, Crockett started in 2004 the 'The Ivory Crockett Run "4" Webster', a fun walk/run.
Crockett has not always been given the credit due to him for what he achieved as a track athlete. Some people questioned his winning of his national titles because rivals were missing, and they even doubted the legitimacy of his world record. This rankled because he was married and had had to battle financial tough times to keep on running. Looking back however, living in West County, Missouri and the father of five children, Crockett could reflect ""Life has been really, really good to me,....Who would have thought this would have happened to me."
