Bernardini's racing career began at age three at Gulfstream Park where he finished 4th in a maiden race. After a lung infection kept him from racing for 2 months, he came back with a 7 length win in a Maiden Special Weight over one mile at Gulfstream. On April 29, he easily won the Grade IIIWithers Stakes prior to going to the Preakness. Bernardini won the 2006 Preakness Stakes by 5 lengths in a time of 1:54.65, in the same race where Kentucky Derby winner Barbaro suffered the hind leg fracture that ultimately led to the Derby winner's death. After his Preakness win, Sheikh Mohammed decided that Bernardini would not race in the June 10 Belmont Stakes, which meant that for only the 4th time in 60 years, neither the Kentucky Derby winner nor the Preakness winner was in the field. A spokesman for Sheikh Mohammed's Darley Stable said that "... climbed the ladder of competition quite quickly" and that "he deserves the break." Bernardini returned to the races on July 30 at Saratoga Race Course with a 10-length victory in the Jim Dandy Stakes over Minister's Bid. On August 26, 2006, he won the Travers Stakes, also in Saratoga, by 7 lengths over Haskell Invitational winner and Kentucky Derby and Belmont Stakes runner-up, Bluegrass Cat. In the October 7Jockey Club Gold Cup, Bernardini earned a 117 Beyer figure in a winning effort. In the 2006 Breeders' Cup Classic at Churchill Downs, Bernardini tracked near the lead and passed the frontrunner, Brother Derek, at the quarter pole. He fought to hold off Invasor at the sixteenth pole but fell short by a length, finishing second. He won the Eclipse Award for 3 Year Old Male of the Year for 2006 and was retired to stud at Darley.

Notable progeny
c = colt, f = filly, g = gelding'' Bernardini's success as a sire has attracted many top broodmares and racemares. On January 26, 2011, Jerry Moss and his wife Ann announced that Bernardini would be the first mate of the 2010 Horse of the Year when Zenyatta was booked to him later that season. She foaled a colt, Cozmic One, in March 2012. He has been a disappointment on the track, finishing badly in both of his starts. Zenyatta's dam and 2008 Kentucky Broodmare of the YearVertigineux produced a debut-winning Bernardini filly named Eblouissante in 2009. Visiting Bernardini in 2012 were 2009 Horse of the Year and American Champion Three-Year-Old FillyRachel Alexandra and 2010 American Champion Three-Year-Old Filly Blind Luck. The 2013 filly produced by Rachel Alexandra, Rachel's Valentina, is a Grade I stakes winner and was runner-up to American Champion Two-Year-Old FillySongbird, and widely considered the second-best two-year old of either gender in 2015.
