Racetrack Conditions & Horse Breakdowns: Expert Insights

Question
Hi, I am currently doing a research project, and I need some answers from experts. Thank you if you are able to answer my question.

Which condition of the racetrack (fast, sloppy, etc.) affects the breakdowns of racehorses the most?

Answer
This question should be answered with accuracy, based on statistics.  Try the AAEP, the American Association of Equine Practitioners, the national vet association.  If no luck there then contact me for assistant.  Thanks, Lora Brown at Dapple lora@dapple.net
