Before I say anything else, let me state that the Triple Crown is the only time I am interested in horse racing. We are going to take our daughters to the Kentucky Derby in the next couple of years. Their interest has been piqued, of course, by the movie Secretariat.
It was a great race, although I will say that I hate to see the Kentucky Derby winner beaten by a horse that did not run the Derby. They call it the Triple Crown, I think you ought to have to commit to run all three races. A few years ago one of the trainers went on a rant when his Kentucky Derby-winning horse was beaten in the Preakness by a horse that had not run the Derby. I sympathize with his point of view.
You can ruin a good horse that is fast enough but not strong enough to compete in all three races. Derby is 1 1/4 mile, Preakness is1 3/16 mile and the Belmont is a mile and a half. That is as long as any of these horses will ever run.
Sham is a sad example. Sham pushed hard, broke the Derby record and still came in second to Secretariat. Did the same thing two weeks later in the Preakness.
They ruined a fine horse when they tried again to push Big Red in the Belmont. Sham could not hold the pace, broke down and finished last. It was his last race.
