Insurance while racing street car?

At the tracks I have been to, the disclaimers are on the entry forms and the admission tickets in black and white. The track is not responsible for any damage or injuries incurred while attending /competing at any event held at the facility.
I also think your private health insurance may have disclaimers for injuries sustained while in a "competition".
I have agreed value insurance from Hagerty and my car is not covered if I race it.
