However, riders competing in a younger age division are not required to move to an older age division once they become eligible to do so.

1. Any cancellation or reschedule of an event prior to race day will have all pre-entry fees refunded. 
2. If an event is interrupted or stopped while in progress, due to weather or other unforeseeable circumstance, it will be deemed final as long as one full lap has been completed. If any individual races are unable to be run on race day, due to the same circumstance, those events will be transferred to an upcoming event where a “make up” race will be scheduled. Depending on the circumstance, the promoter may opt to do a complete make up event at their discretion. Refunds will not be given for any race that completes a lap or is rescheduled for a make up date. Refunds will only be given for a complete cancellation of a date. Please check weather conditions before heading out to any event and be sure you are comfortable with the conditions. 
3. If after the parade lap, you feel uncomfortable with course conditions, weather conditions, your personal or machine condition, or anything else, you may proceed directly to the sign-up trailer for a refund or future event voucher (at the promoters discretion).
