Boundary is one of over 100 stakes winners bred in the name of  Claiborne Farm and William Haggin Perry’s The Gamely Corporation.  Perry, a friend and associate of Claiborne Farm for more than 40 years, passed away at the age of 85 in 1993.  A handsome son of Claiborne stallion Danzig, Boundary was one of the last horses to represent that great partnership.

Racing in the name of Perry’s widow, Nicole, Boundary was conditioned by Hall-of-Fame trainer Bill Mott and sprinting was his specialty.  Never asked to go beyond seven furlongs, Boundary won six times and placed twice in eight starts at three and four.  He won his first five starts, including Belmont’s Roseben H.-G3, and then placed in the Tom Fool S.-G2 and True North H.-G2. In the latter, he was closing fast to only lose by a nose at the wire.  Boundary won his final race, the A Phenomenon H.-G3 at Saratoga.  He turned in a stellar performance, defeating eventual divisional Champion Cherokee Run by a half-length.

Boundary entered stud at Claiborne in 1995 and sired 16 stakes winners, 48 stakes horses, and the earners of more than $21 million.  His leading runners include 2008 Kentucky Derby-G1 winner and Champion 3-year-old colt Big Brown; 2000 Champion 2-year-old colt in England and Ireland Minardi; record setter and multiple Grade 1 winner  Pomeroy; multiple GSW Conserve; and a trio of millionaires in Japan.

Boundary was retired from stud duty due to declining fertility in 2005. He lived out his life as a pensioner at Claiborne until his death on February 6, 2012. Boundary is buried at the farm.
