Cajun, I had two horses train and race over the PolyTrack surface and I can say without a doubt that the surface is much kinder to the horse. They have studied this extensively over in Europe. There is not enough data on PolyTrack runners going to dirt or to turf yet. We need about 3 racing seasons to figure that out. But the horses I have co-owned are much more sound when training and racing on PolyTrack. I just had a horse race at Mountaineer and she finished 2nd last weekend. She has since worked over the track at Mountaineer and she came back sore. So we are shipping her back to Turfway to work.
