Our purpose is to support a safe and enjoyable race experience for all. Our class structure is configured to accommodate the most common of bikes in our area. We are attempting to create rules that will transfer between other racing organizations in which our members will ordinarily race with. .

Rules and Regulations


Code of Conduct

The NMRA expects riders to engage in proper conduct to resolve differences between parties in the spirit of good sportsmanship. If a conflict between two riders cannot be resolved in that spirit, it is to be brought to the attention of the organizer of the NMRA by one of the riders involved. Both (or all) riders involved in the conflict are required to attend a meeting with the organizer. Involvement by the organizer will automatically put all riders involved on notice that the NMRA code of conduct will be adhered to under threat of penalty.

Problems with a rider's conduct are to be brought to the attention of the organizer of the NMRA by the affected rider directly involved in the incident. All parties will conduct themselves in a quiet, professional and courteous manner. They are to articulate their point without emotion, profanity, or creating a scene. The failure by either party to comply will result in penalties accessed for their conduct during the meeting in concurrence with penalties accessed for their actions on the track.

The organizer will meet with the riders directly involved with the incident only, no other individuals may be present. If an individual(s) not involved interferes with the meeting, the rider with whom the individual is associated will be penalized regardless of the findings.

Riders who threaten physical violence to any rider, track employee, race organizer, spectator or any other persons may be ejected from the track for that event.  Riders who engage in physical violence will be ejected from the track and not allowed to attend future NMRA events.  Collective information from the track officials will be gathered on each rider in the incident. The total tally of incidents involving each rider and the severity of their actions will be considered in the call. Each party may be penalized by the findings. Decisions by the officials are final, there is no recourse or review. 

If a rider is found to be a danger to other riders on the track they will be warned and/or removed from race events at the discretion of the race director. There is no appeal of this process. If a rider is found to be a danger to riders at multiple race events they will not be allowed to participate in further NMRA events.
