The epic saga of the riveting rivalry that enthralled a nation and spawned history’s most thrilling Triple Crown chase. Affirmed and Alydar are as inseparably linked in legend as they were on the racetrack. Bound from conception by shared bloodlines of the great Native Dancer, this peerless pair of chestnut colts traded wins multiple times even before their showdown in the 1978 Kentucky Derby spurred an unmatchable rivalry that transcended the Triple Crown and the Sport of Kings itself. Their intertwined tale is a study in contrasts as stark as David and Goliath. If Alydar and his human connections personified racing royalty, Affirmed and his team embodied all the underdog outsiders who’ve had to claw their way into the winner’s circle. Alydar was born into Bluegrass aristocracy as the royally bred pride of Kentucky’s Calumet Farm, the old-money dynasty that had reigned over the Sport of Kings the same way the Damn Yankees dominated the national pastime. Affirmed, meanwhile, was born into the obscurity of a Florida farm funded by the new-money millions of a controversial Wall Street financier turned nouveau breeder. Contrasting styles made their differences even starker: the laidback Affirmed, all streamlined elegance, gliding with the grace of a deer and the heart of lion, versus the bullish Alydar, all massive muscle and machismo, stalking his nemesis while gearing up to unleash his fearsome closing kick. Riding on their backs were the dreams of colorful human personalities caught up in a battle of wits and wills: Lucille Markey, racing’s grand dame entrusting her last chance at restoring Calumet’s faded glory to John Veitch, a young Kentucky-bred trainer with a Hall of Fame pedigree. Lou Wolfson, the pioneer corporate raider staking his post-prison shot at redemption on journeyman trainer Laz Barrera, a charismatic Cuban immigrant with a knack for charming the best out of longshots like Affirmed. And, most famously, Steve Cauthen, the teen phenom celebrated as the world’s top athlete even before riding Affirmed into the Triple Crown cauldron. The Kentucky Derby may be hyped as “the most exciting two minutes in sports,” but Affirmed and Alydar’s electrifying stretch showdowns only kept intensifying through both remaining jewels—the Preakness and the Belmont Stakes—of history’s hardest-fought Triple Crown series. Duel for the Crown vividly tracks these two magnificent Thoroughbreds through every hoofbeat of their odyssey, climaxing with the Belmont stretch duel in the greatest race ever run as they desperately gallop head to head all the way to the inevitable photo finish—and beyond, into history and immortality.
