"race of Champions" So, what former champions are going to this event. Do you have any ROAR National Champions going or IFMAR World Champions going? If you call it a race of champions I believe those should be some of the people attending.
When a tack has only been getting like 20 people to race adding a fancy name is really not going to help too much. It will only irritate those who drive a ways to go and see a small turn-out.
