Sired by Chieftain, a son of Bold Ruler, in turn a grandson of Nearco, Fit to Fight was out of the mare Hasty Queen II, the 1983 Kentucky Broodmare of the Year.
The following year he was second to A Phenomenon in the Vosburgh Stakes but ahead of third-place finisher, Deputy Minister.
Fit to Fight finished behind winner Slew o' Gold in the voting for 1984's Eclipse Award for Outstanding Older Male Horse.
Retired from racing, in 1985 Fit to Fight became one of the original stallions to stand at stud at Lane's End Farm in Versailles, Kentucky.
The sire of 39 Stake race winners, he was pensioned in 2005 and sent to retirement at Blue Ridge Farm in Middleburg, Virginia.
