Breed my own race horse?

I have a fairly well bred TB mare, she is registered with Wetherbys and parentage tested. I am considering breeding her to a racing stallion (he's not won much but it will be fairly cheap) by natural covering. Checked for inbreeding, there isn't any for 5 generations. Other than registering the foal with Wetherbys and sending him/her to a reputable trainer at about 2 years old...and hope for the best...is there anything else I need to do?? Racing and TB breeding seems to have so many rules and regulations, have I forgotten something? Of course, the foal may be useless as a racer, in which case I use him/her as a riding horse, but you never know?
