As long as there is perfect weather (no extremes of temperature or moisture)and the synthetic tracks are maintained constantly, they are probably (almost) as safe as dirt tracks. Factor in any extreme weather or more than a month of racing/training on them and they start to fall apart fast. Basically, as long as you don\'t run horses over them, they\'re fine! Hey, that\'s not too bad for the millions they cost to put in and maintain, right? Factor in that you now only need change the entire focus of the breeding and training of horses for the last 100 years, take the brilliance and power out of the thoroughbred animal, and you\'ve got paradise - or - Southern California racing as the case may be.
You couldn\'t have two better examples of the impact of synthetic tracks on racing as Curlin and the whole Rachel/Zenyatta morass. Curlin, one of the most perfect-looking, moving thoroughbreds that has ever been produced floundered over the surface to a bunch of animals he would have cruised by on any dirt surface on any day in any weather. The two best fillies in a long time may not meet in the Breeder\'s Cup (the whole purpose of the Breeder\'s Cup in the first place) because horses like Rachel don\'t usually perform well over synthetic tracks. So we shouldn\'t aspire to breed/develop horses like Curlin or Rachel! Certainly not if we\'re racing on synthetic tracks.
All they should ever have been used for is at training facilities where owners/trainers have the option of training certain horses that might benefit over the surfaces. It is a complete joke what has happened out there, but what would you expect from a state that allowed trainers for years and years to get away with all conceivable methods of chemically improving a horse\'s performance with everything from steroids to milk-shakes to God-knows-what with not so much as a slap on the wrist.Everyone knew who was doing what and no one said anything. Then when the animals break down and get sent to Mexico to be slaughtered, and people looked for something to blame, they came up with the thesis: it must be the dirt!
