But our mania for speed has made these great, delicate beasts all the more brittle. All 20 horses in the Derby were descended from one great sire — Native Dancer, magnificent gray who lived but a half-century ago. Add to this inbreeding the fact that today drugs are allowed in the United States that are banned most elsewhere, so horses that have no business racing do, and then go to stud and pass on their weaknesses.
Speed, speed. European horses run more tactical races. We just go flat out.
Sterling Moss, an old star of another type of racing, Formula One, once explained it this way: "You see, we have an entirely different concept of speed in Europe. It's relative. You arrive at a 60-miles-per-hour corner, for example, and try going around it at 61. Then you'll know what speed is."
