September 26, 1965: You think the current Nextel Cup season is too long or has too many races? On this date, Junior Johnson wins the Old Dominion 500, the 50th race of the 1965 Grand National season. Johnson leads 481 of 500 laps on the half-mile Martinsville Speedway oval. Richard Petty, who finishes second, leads the other 19. One last note: There were 55 races that season.
