General Rules

ENDURO HIGHLIGHTS—Welcome drivers to the fun and excitement of Enduro Racing. Here is what an Enduro is all about. SPEED does NOT necessarily count in an Enduro. The secret is the combined ability of a driver and their car to last for 100 laps or one hour, on the race track without a major mishap. This is NOT a Demolition Derby. The first car that completes 100 laps will be the winner, or the car that travels the most amount of laps in one hours time would be declared the winner.

This is an event for the basic “STOCK CAR.” Only minor modifications or alterations will be allowed. The race will start with two or three cars abreast in each row from a rolling start, and continue for 100 laps or one hour, without any yellow flags (unless deemed necessary by officials for safety reasons). Cars that are stalled on the track due to breakdowns or accidents may be left there as obstacles, and all other cars should avoid them while continuing to race. The driver must never get out of their car while it is on or near the racing surface. Violators will be disqualified and ejected from the race immediately. The driver may get out and observe the race from the safety of the infield. Once again, this is an endurance race event, NOT A DEMOLITION DERBY! The best strategy is to pace yourself and stay out of trouble, don’t crash into anyone and try not to let anyone crash into you. Start with a good set of tires and avoid running over anything that will cut them.

The RED flag will be displayed only in case of an emergency, and all cars MUST STOP IMMEDIATELY and hold their position. The race will restart with all cars in the position they were in at the Red flag. If your car catches fire in the engine compartment, go to the infield and get out of it immediately. The fire crews will extinguish the fire quickly. No cars will be allowed out of the pits during a RED flag. Cars that have flat tires or need servicing, may go to the pits on the GREEN flag. If you enter the pits on a RED flag, you will be held at the pit entrance for one minute once the green flag flies again. Re-entry to the track will be allowed as the ramp officials indicate. Driver changes will be allowed only when the car is in the pits. Cars entering the pits must slow down and proceed in an orderly fashion with safety in mind. There is a $25 fine and/or a five lap penalty for speeding in the pits. Any car that cuts through the infield will be BLACK flagged and/or assessed a five lap penalty. Rupture of gas tank and/or fuel spillage will require immediate BLACK flag. Any loss of wheel or tire requires your leaving the race track immediately, either to the pits for repairs or park in the infield. Officials will assess lap penalties or disqualify cars that are in violation of procedures, specifications or safety, and their decisions shall be final.
