Fault Definitions


Failure Definitions


Other Penalties


Maximum penalty in any section without a failure shall be 3 points, with a failure it shall be 5 points.


Marking in subsections shall be with the front wheel entry and exit from the subsection denoting the subsections in which points were lost.


Riders will be considered to be in the Observed Section after the centre of the front wheel has passed the Starting Line and until the centre of the front wheel has passed the Finish Line.


In any given section, a rider must always be travelling forward in the direction of the section. Thus a rider may not cross his own tracks unless the section is of the horseshoe or rejoining type wherein a common piece of terrain is used for two different “pieces” of a section.


Where the section is not marked completely by tape or other physical markers, the riders must ride between consecutive gates. (Gates shall be defined as a left hand marker and a right hand marker).

The boundary between consecutive sets of gates is a straight line, left hand marker (blue) to left hand marker (blue), or right hand marker direct and straight line to next right hand marker.


No section may be changed. If a section becomes unusable the Clerk of the Course may reduce the number of laps required on this section. This number must not be reduced to less than the maximum number of laps already covered by any rider.


To be classed as a finisher, a rider must attempt every section the required number of times and in the correct order. Crossing any section boundary shall be deemed an attempt.


In the case of a tie with no points lost, the result will be a tie. In the case of a tie with points lost, the most sections “clean” shall be considered the winner, if still a tie, the rider with the most sections at a loss of one point shall be the winner. If still a tie, the rider with the most sections at a loss of two points shall be the winner, etc. If a tie with points lost cannot be decided in this manner, the rider with the best score the longest shall be the winner.

“Sections” refers to most ride clean, i.e. if, there are 10 sections ridden 5 laps, it is the most of 50 rides or sections, not the most of 5 sections clean.


A record of points lost by all participants shall be kept at each section and/or on cards carried by each rider on which their score is recorded by the checker.

– It is the rider’s responsibility to see that their score card is properly marked and turned in on time.

– In case of disputes where the dual system is used, the master sheets from the individual sections are considered to be the official score.

– When the official score is the rider card only, sections not “punched” will be considered as missed. If cards are lost or unreadable the rider will be marked dnf.


When a time limit for the event is established (mandatory for National Championships) checkers must remain at their post until the limit for the last rider has expired, or they have been advised by the Clerk of the Course that the rider has withdrawn.

The Clerk of the Course may only accept a statement from the rider or his crew as official notification of withdrawal.


Organizers must send all entrants a copy of the results within 14 days of the trial. Organizers may require the rider to supply a stamped, addressed envelope in order to receive the results.


Team points shall be based on the rider’s position in his class – (i.e. 1st class 1 pt., 6th class 6 pts.) A DNF will score points equal to the number of starters in the class. The points shall be added and the team with the least number of points shall be the winner.




No riding on the course within ten (10) days prior to the event.


Competitors shall ride all sections consecutively in the numerical sequence as laid out. Competitors may start at any section they wish, unless directed otherwise by the organizers.


Riders must not start into a section until signalled by the checker.


Abuse of any official (including checkers) will result in disqualification.

Time and Observation Trials



The riders start at approximately one minute intervals, the course is 30-40 miles in length, with riders negotiating approximately 10-15 observed sections per lap, the number of laps to be determined by the organizers.


There are three main awards:

National Championships



A time limit will apply to all National Championship Rounds. This will he determined by the organizer.


A National Steward shall he assigned to all National Championship Rounds. Assignment of Stewards to non national events shall be at discretion of head office.

The assigned steward/clerk of the course has the authority to reclassify a rider if they have entered a class inappropriate to their skill level. This would normally only take place for safety or fair play reasons and after discussion with the rider involved. Special care needs to be taken when moving a rider to a lower class, that it does not jeopardize the chances for other riders in the class to win the championship.


When arrows or gates are used:

– red arrows on the right

– blue arrows on the left


National Championship and International events will not be awarded to organizers unless they have demonstrated organizational competence through the operation of region ally sanctioned events. The required number of regional events will be established annually.



The classes to be run at individual championship rounds will be determined by the Board depending on the level of difficulty of the planned sections and the rideability of the loop. Assessment will be based on previous events and available information from the applicant.


Classes must include Veteran and Super Veteran.


The lines to be ridden by Veteran, Super Veteran and Grand Veteran classes will be determined by the organizer. This information must be included in the pre-entry form.


Expert Class is open to any rider of Advanced or Expert skill level. They will ride a combination of approximately 30% Champ sections and 70% Advanced sections. This will be designated by a card at the start of the gate indicating either E-C or E-A.


Sections may be pre-inspected, on foot, at a time established by the organizer. The inspection shall be carried out by riders nominated by the CMA (max. 1 per class) in the company of an event official.
