Derby Week Horse Story

From the SI archive, a reflection on Secretariat's life, by William Nack, who wrote the book from which the movie Secretariat was based:

Just before noon the horse was led haltingly into a van next to the stallion barn, and there a concentrated barbiturate was injected into his jugular. Forty-five seconds later there was a crash as the stallion collapsed. His body was trucked immediately to Lexington, Kentucky, where Dr. Thomas Swerczek, a professor of veterinary science at the University of Kentucky, performed the necropsy. All of the horse's vital organs were normal in size except for the heart.
"We were all shocked," Swerczek said. "I've seen and done thousands of autopsies on horses, and nothing I'd ever seen compared to it. The heart of the average horse weighs about nine pounds. This was almost twice the average size, and a third larger than any equine heart I'd ever seen. And it wasn't pathologically enlarged. All the chambers and the valves were normal. It was just larger. I think it told us why he was able to do what he did."
In the late afternoon of Monday, Oct. 2, 1989, as I headed my car from the driveway of Arthur Hancock's Stone Farm onto Winchester Road outside of Paris, Ky., I was seized by an impulse as beckoning as the wind that strums through the trees there, mingling the scents of new grass and old history.
For reasons as obscure to me then as now, I felt compelled to see Lawrence Robinson. For almost 30 years, until he suffered a stroke in March of 1983, Robinson was the head caretaker of stallions at Claiborne Farm. I had not seen him since his illness, but I knew he still lived on the farm, in a small white frame house set on a hill overlooking the lush stallion paddocks and the main stallion barn. In the first stall of that barn, in the same space that was once home to the great Bold Ruler, lived Secretariat, Bold Ruler's greatest son.
It was through Secretariat that I had met Robinson. On the bright, cold afternoon of Nov. 12, 1973, he was one of several hundred people gathered at Blue Grass Airport in Lexington to greet the horse on his flight from New York into retirement in Kentucky. I flew with the horse that day, and as the plane banked over the field, a voice from the tower crackled over the airplane radio: "There's more people out here to meet Secretariat than there was to greet the governor."
"Well, he's won more races than the governor," pilot Dan Neff replied.

The article is excellent.
