RIDING NUMBER / COLORS:  Earliest entry gets 1st choice. NO exceptions.  To assure accuracy in scoring, we do not allow duplicate numbers. If you are assigned a new number, you must use it … you may need to change, so be prepared. Be sure to fill in your second choice or we will assign a number you must use if your first choice is not available.

*****MINORS*****:  Parent, legal guardian or "authorized adult" must complete minor release. In the case of "authorized adult", he/she must provide notarized legal documentation of said authorization of guardianship with minor release to clerk at registration or with pre-entry.... Download/print the form HERE.  This form is in addition the the release required of all riders.  Moto-Mgmt., LP will retain original said documentation as property owned by them. Authorized adults should retain a copy for their own records or needs. All persons signing a minor release must remain with said minor until the conclusion of the event or until competition is complete.  All persons signing any release with minor must be prepared to show proof of identity and guardianship.

NO LATE SIGN-UP:   No exceptions. A $20 fee per class will be accessed to those requesting any class change.

STARTING PROCEDURES:  NO TOOLS SUCH AS, SHOVELS, RAKES, ETC..   There is NO farming in front of the rear flat metal bar of gate. Please do not dig holes at the starting line for dirt or pile dirt into the gate mechanism. You MUST be IN FRONT of the metal back up pipe. It is your responsibility to know the correct starting procedures. Per rider and machine, only one mechanic allowed in staging.

PRACTICE:  The staging area will be used to stage all groups for practice. There is no starting from the sidelines. You must have your armband & practice sticker before you will be allowed on the track. There is no riding off course or turning around to retry an area during practice. This is extremely dangerous. You must ride in the practice designated for your bike & skill level that we will assign. Do not ride in the wrong practice. Violators will be penalized 5 full seconds, PER infraction.

EXIT:  Any rider leaving the course for any reason during a moto must return to the track safely, at a spot closest to his/her point of exit, without bettering his/her position or endangering other riders, spectators or Track Officials. Penalty may be one lap or disqualification to be determined by the event official and depending on circumstances contributing to the incident.

DIVISIONS:  If your class should have a division split. The amount of riders in your class will determine the number of divisions and consi races. There are no points awarded for the consi race.   The consi race only earns you a spot on the gate. Your first moto divisional race counts for score as your first moto. That score will be added with your second moto score for your overall race. Check the posting board for the division you will ride in AND consi if your classes have divisions. THIS IS YOUR RESPONSIBILITY!!!  If you miss your division race you will NOT be moved or permitted to compete in a different division ... You will have to go directly to the assigned consi ... no exceptions.  The posting board will also tell you how many divisions and the number of riders that will be taken from the division race and put directly into the 2nd moto. It will also tell you how many consi races there are for your class and how many will be taken from the consi race to the 2nd moto.  Please note that the number of divisions does not always equal the number of consis.

SCORING:  The following applies at ALL Lake Whitney MX Park events. You must complete one full lap to be considered to have raced the event. If not, it will be considered that you DNR (did not race) and you will receive a score equal to a DNS. Riders who DNS (did not start) will receive a score equal to the number of riders in the class PLUS 30. DNF (did not finish) … Riders who do not take the checkered flag OR at a minimum, complete one lap, but not 1/2 the laps of the class winner will receive a score equal to the number of riders in class (minimum 20 points), regardless of whether or not you take the checkered flag.

PROTESTS:  Any mechanical or age protest must be submitted in writing, signed by a rider in the same class & submitted to the event clerk (not the official) at the scoring tower within 15 minutes of the completion of the moto, decisions will be rendered in a timely manner as best we can. Protest of rider age or a clerical protest will have no fees assessed. ALL protests regarding scoring or administration must be done within 30 minutes from the time the scores for the first moto are posted… 20 minutes applies to the second moto. Protest of legality of a machine is $35.- (non-refundable) plus $100.- per item that is being protested (top-end, front suspension, carburetor, etc.)  The $100.- per item fee will be awarded to the prevailing rider. Riders may ride under protest if a decision has not been made, but may still be disqualified upon final decision. If a bike should be protested, the rider has the right to have his bike impounded and held until the final moto of the day has been completed. Bike will be torn down at this time to determine if it is legal. The official may at anytime, upon VISUAL inspection, declare a bike illegal for the class entered. The rider associated with the bike shall be disqualified.  Decisions of the event official are FINAL, for both race and technical infractions.

!!! There is NO PASSING, NO JUMPING or aggressive riding under/on a yellow flag. Please slow down and use caution, have respect for the downed rider, and authorized persons attempting to assist him. Do not start aggressive racing again until you are at “safe distance” away. Rescue efforts must be left to authorized officials only on the track. Violators WILL at a minimum, be docked one lap.
