Health insurance and motorsports

I’m in the process of getting a car and team together to go sprint car racing next season here in Virginia.

I was wondering if anybody knew what the health insurance implications are with autoracing. If I would need some kind of medical attention what insurance if any pays it. Would my health insurance cover that or would they say I’m on my own because I was participating in a potentially dangerous activity.

Does anybody know of any motorsports add on health insurance policies available if regular health insurance doesn’t cover it.
