Race Day Format

• Racers of all age and gender will compete together in the heats. Racers will be placed in a heat group based on check-in order (early and late). We will run 1 round for both groups and then as time allows we will run additional rounds.

• The top 12 racers (lowest average time) from the heats groups (6 from early and 6 from late) for the rounds mentioned above will compete in a championship round to determine the days top 3 fastest finishers.

• All racing participants for a heat group will be asked to sit together in the Pit Area.

• Upon notification, each racer will take their car from the Pit Area to the Starting Gate. The Starter will then position the car at the starting gate, and the racer will take his position at the Finish Line to await the running of the race. Following the heat, racers will then be asked to return the car to the Pit area and wait for their next race.

• In the event a car jumps the track (as determined by the track officials) we will re-run the heat. If the same car jumps the track a second time, but crosses the finish line its time will stand. If it does not cross the finish line, the racer shall have 5 minutes to make repairs and then get a 3rd and final attempt. If the 3rd attempt the car does not cross the finish line it will be awarded a final time of 5.0 Seconds.

• If there is a problem with the timing measurement of any lap, the race organizers will rerun the lap until a successful timing is achieved.

• Any car that is damaged during a race or in the transfer of a car to/from either the starting or finishing gate will have 5 minutes to repair the damage, and we will re-run the heat. If the car breaks down a second time during a race but crosses the finish line its time will stand. If it does not cross the finish line, the racer shall have 5 minutes to make repairs again and then get a 3rd and final attempt. If the 3rd attempt the car does not cross the finish line it will be awarded a final time of 5.0 Seconds.
