ALL D Class Riders:
During a series if a rider receives 4 wins or 5 second place finishes or any combination of the two (must be a miminum of 10 riders in the class) the rider will be advanced at that time. At the end of the year all D class riders who have won an event will be advanced as of December 31. If you’re fast enough to win the D Class, then you need to start the series in the C Class. If a rider has previously won a championship in any series any class (excluding Women & Girls) that rider has to advance by December 31 that same year. When you get advanced, you don’t take your points with you. The D Class is a beginner class and a chance to try racing to see if you like it. It isn’t a place to plan on winning a championship.

No Sandbagging:
If it is determined by MCMX staff that you were sandbagging you will be immediatly advanced.

Youth D Class Riders:
You can race a 2nd class, but if you place in the “TOP 30%” you will be out of the D Class. This Youth Rule is based on 10 rider minimum class.

Series Tie Breaker
If a tie is recorded in the final point standings the tie breaker will be the best finish in the last event that either or both riders attended in that series.
