Although North America has a number of prestigious strongman events determining the "Strongest Man in America", the "Strongest Man in Canada" and the "Strongest Man in North America", the All-American Strongman Challenge has added kudos because it is open to entrants from overseas with the potential to bring in leading international competitors as well.  It is notable for the calibre of entrants it has attracted, with many World's Strongest Man finalists being represented. The 1980 World's Strongest Man was the fourth edition of World's Strongest Man and was won by Bill Kazmaier from the United States.  It was his first title after finishing third the previous year.  Lars Hedlund from Sweden finished second after finishing second the previous year, and Geoff Capes from the United Kingdom finished third.
