The cover of his book The Complete Book of Running featured Fixx's muscular legs against a red cover. The book sold over a million copies. In 1980, Fixx wrote a follow-up book titled Jim Fixx's Second Book of Running: The Companion Volume to The Complete Book of Running. In 1982, Fixx published Jackpot!, the story of what happened after the publication of The Complete Book of Running when he experienced the "Great American Fame Machine", becoming richer and more celebrated than he could have imagined.
