It is the competitor's responsibility to retain a copy of and understand the most current version of the rule book. The most current version of the book will always be available here. Select updates will be explained in separate posts. The 2017 rule book PDF includes the rules, appendix A, class structure and track map and race format for each round. We recommend downloading a copy to your phone or tablet so you always have it handy.
