Traditional Enduro/Time Keeping

In a traditional time-keeping enduro, riders leave together in groups or rows, and each row starts at a certain minute. The object of the event is to arrive at pre-defined checkpoints according to a strict schedule. Early or late arrivals result in the riders' scores being penalized. Throughout a day there will also be allocated periods for refueling and servicing the machine. Penalties apply for not meeting defined times or for outside-assistance when not permitted.

Both District 4 Enduro Timekeeping enduros are co-sanctioned with the East Coast Enduro Association and require an ATV Registration/plate and a working headlight and taillight.

You will also need a roll chart holder, odometer, and a watch.

AMA Racing Rulebook Section 2.5 pg 87-99

 

A. General

1. An enduro is a meet in which speed isn't the determining factor and a time schedule must be maintained. It takes place on a variety of terrain, little-used roads and trails, etc. Where the course crosses private or public land, the organizer must obtain permission from the landowner or land manager. The use of an active railroad right-of-way is prohibited. However, if active railroad tracks are crossed, a mileage reset should be provided immediately after the crossing to allow any riders delayed by a train to regain lost time.

2. Definitions when referring to Enduros:

    a. Emergency check: The same as a secret check, except that minutes and seconds are recorded and used for breaking ties.

    b. Gas available: A gas station, or a location where a rider’s own fuel is provided.

    c. Gas stop: A place designated on the route sheet by mileage and the words “gas stop."

    d. Known control: A timed checkpoint whose location is known to all participants.

    e. Observation check: An unknown checkpoint where no time penalty is recorded.

    f. Secret check: An unknown, timed checkpoint.

    g. Timed check: Any secret check, emergency check or known control.

    h. Start control: A timed checkpoint designating a starting or a release point. A point whose mileage and key time are listed on the route sheet. A timed check immediately preceding a start control may be located without regard to the 3-mile check separation rule, but the timed check immediately following a start control must meet the 3 mile check separation rule.

    i. Restart Enduros must use at least 2 Emergency checks. The combined total seconds at these checks are to be added to the final score.

3. No enduro may be more than 24 hours of continuous riding. In any 24-hour meet, there must be two or more scheduled stops of at least 30 minutes each.

4. There must be at least one gas stop or gas available location for each 50 actual ground miles (33 actual ground miles for a National Enduro).

5. The organizer is responsible for clearly and properly marking the course. Two markers shall be placed at each turn, and shall be identified by number or mileage to conform to the route sheet. Restart Enduros mileage markers will be placed every other mile if not with the arrows. At least one marker must be placed every half mile on straight stretches. In the case of the course coming close to itself, there must be banner tape and “wrong way” markers to ensure riders do not get on adjacent course.

6. Danger markers must be posted far enough ahead of hazardous conditions to allow the fastest riders enough warning to stop. The year of the meet must be indicated on each marker. A member of the promoting organization must proceed ahead of the first rider to make sure all markers are in place.

7. An AMA member who defaces, changes or destroys markers, or who is responsible for having such damage done, will be permanently suspended from the Association. Within two weeks after the enduro, the organizer must remove all course markers.

8. At any enduro in which the rider carries his scorecard, the cards of trophy winners may be checked against the backup sheets. A three-person committee that includes the referee must rule on discrepancies between the scorecard and the backup sheet. At National Enduros, if there is an AMA staff member attending, he/she must be on this committee.

9. A rider may enter an enduro, including a National, only once.

B. Classification of Riders

1. National Pro riders finishing in the top 15 of the preceding year’s National Enduro Series are designated as Pro riders for the following year. A rider in this class is eligible for overall high-point winner and Pro trophies, but not for A class awards.

2. If no Pro class is run, Pro riders may compete only for the overall win. Any A rider may submit to the AMA a letter of intent indicating that he/she wants to be designated a Pro rider for the calendar year.

  •   3. District organizations that want to establish a Pro class must submit a detailed description of proposed rules for AMA approval. The deadline for this proposal is Dec. 15 of each year 

  • C. Equipment
  • 1. A rider may not start if any state-required equipment isn't in working order at the beginning of the meet.
  • 2. Motorcycles must be equipped with a U.S. Forest Service-approved spark arrester, as part of the muffler or in addition to it.
  • D. Race Program
  • 1. Riders may not ride on a marked course under penalty of disqualification, except a rider competing in an event running the same course.
  • 2. If there is a sidecar class, the pathfinders should cover the marked course in a sidecar.
  • 3. Riders must comply with all applicable local and state laws and regulations, including speed limits. At the request of an official of the meet, a rider must show a valid driver’s license. If a qualified, identified official observes a rider violating a safety regulation such as entering a public road without first stopping, the rider may be disqualified on the spot. A notice that this rule is being enforced must be posted at the start of the event. Any rider who receives a citation for a moving violation will be disqualified immediately. OFF-ROAD 2.5 90 4. The motorcycle must cover the course under its own power or by the physical energy of the rider. Towing, as well as organized repair and service (except at scheduled control rest periods), is prohibited. Violation will result in disqualification. Riders may assist one another on the course, although a rider who ceases to be a contestant may not help another rider.
  • 5. A route sheet is given to all riders no less than one hour before the start. The sheet must list key time for the event, the key times for all known controls and the exact mileage and schedule in miles per hour between these controls. It also must give the exact cumulative mileage at turns and the direction of turns. The route sheet lists the mileage for any official gas stops and gas available locations.
  • 6. If speed averages change during the event, the sheet must provide the exact mileage and key time for the point where the speed changes. The mileage at any point where the speed average changes is computed from the last known mileage in whole tenths of a mile and the time is computed to a whole minute.
  • 7. Starting positions must be determined by a random drawing. A separate random drawing may be used to allow placement of pre-entered C riders behind preentered A and B riders. At the starting time, one minute after the key time, the starter starts up to five riders each minute. If there are fewer than 100 riders in the meet, the starter sends out as many as two riders on each minute.
  • 8. Enduros may use dead-engine starts.
  • 9. Riders must remain on the marked course. A rider who leaves the course may continue the meet only by reentering the course at the same point. A marked course shall mean the following: In sight of the marking arrow, except that when traversing double marked sections the rider must remain between the markers.
  • 10. If motorcycles are sealed throughout the meet, it must be done by officials at the starting control and removed by officials at the finish control.
  • 11. If teams are recognized, they shall consist of riders who all are AMA members. A club team consists of riders who all are members of the same AMA-chartered club. Sidecar or buddy seat passengers aren't considered as team members. Team competition and the number of riders required should be noted on the official entry form. Riders may compete only on one team.
  • 12. An odometer check must be placed 2.9 miles from the start to allow riders to calibrate their odometers to the one used in laying out the course. An odometer check will not be mandatory at a Restart Enduro as they have mileage markers every other mile.
  • 13. Check Stations must display the key time and the accumulated mileage to the check. All timed check points must use a flip card.
  •     a. Check stations shall use the following markers,                       measuring at least 18-by-18 inches with a 10-inchhigh           black letter:
  •            (1) Known control: Yellow marker with a K.
  •            (2) Observation check: White marker with an O.
  •            (3) Secret check: Red and white diagonal marker with                  a S.
  •            (4) Emergency check: Green and white diagonal                         marker with an E.
  •            (5) Start Control: Yellow and white diagonal marker                      with black marking “ST."
  • 14. These markers designate the exact checking point. Timed emergency and secret checks are combined and     display only the emergency marker. Scores are computed as though the check stations were operated separately. Emergency checks may not be combined with known controls.
  • 15. Checking time is taken the instant a motorcycle’s front wheel arrives opposite the marker, or when a rider stops moving forward and is identifiable within sight of a timed check. Checkers may not leave a check station to try to identify a rider. Putting down one’s foot doesn't signify the point of timing, but time is taken if a rider zigzags or paddles to stall for time.
  • 16. The finish point must be a Known Control, and if the scheduled Rest Stop or Gas Stop is also a checkpoint, it too must be a Known Control. Final scoring may be a secret check prior to the finish. Under this option, an organizer may also have an observed check at the finish point. However, these conditions must be explained on the route sheet.
  • 17. Check stations may not be more than 40 miles apart. Timed checks must be at least 3 miles apart. Timed secret or emergency checks must not be less than 2 miles before or less than 3 miles beyond a gas stop. When check stations and controls are within a town or city, they must be placed at the entrance to the municipality and located where contestants will not be needlessly delayed by traffic lights, speed limits or congestion. An observation check may be located on any part of the course.
  • 18. At all checking stations, except observation checks, there will be at least three officials. One shall act as timer and call the time of arrival or departure. One shall insert the rider’s time and number on the backup sheet and one shall mark the rider’s scorecards. It is the rider’s responsibility to ensure that his scorecard is properly marked and that he is listed on the backup sheet. A register of riders and times (backup sheet) must be kept at all timed checking stations, and a register of riders must be kept at all observation checks. These registers are to be used in case a question on scoring arises at the end of the meet. Any rider changing entered time or entering his own time on either the scorecard or backup sheet will be immediately disqualified.
  • 19. If a timing device is discovered to be inaccurate by five or more seconds, or if any timing device fails, that check station will be considered an observation check only. If an error in mileage, time or placement of a checkpoint, scoring irregularities or course irregularities occurs, the check must not be adjusted and will be used only as an observation check. Missing an observation check is the same as leaving the course.
  • 20. Mileage resets (added mileage to give riders time) are considered official route sheet mileage and this mileage may be used to place subsequent timed checks. If a reset is used at a gas stop, it must be placed at least 1/10th of a mile after the gas stop. Resets aren't used to increase the official length of the enduro. Reverse resets (mileage subtracted to make a rider late) are prohibited. The accepted standard variation for enduro mileage accuracy is no more than 0.02 mile as measured from the last known mileage. If a protest is filed on the mileage at that point, the average of three motorcycle’s odometers will be used to determine the mileage in question. Preferably, the three motorcycles will include the protester’s machine, the layout mileage bike and one other.
  • 21. Check stations must open 30 minutes before the first rider is due, and remain in operation until one hour and 59 seconds after the last rider is due to arrive and depart. When the check station closes, the backup sheet is signed and delivered to a point designated by the referee. If the validity of a check is questioned because course markers are missing or altered, that check may be declared official if more than half the riders in contention at the preceding check reached the check in question. If because of difficult conditions an enduro has no finishers, the riders who reach the farthest time checkpoint within their time limit will be scored. If circumstances force a run to end before the finish, the last timed check station used prior to the intended end of the meet will be considered the end, and scoring will be completed at that check.
  • 22. The mileage at any timed check is computed in whole tenths of a mile, and the time to that point is computed to a whole minute. A rider arriving at a timed check within the 59 seconds after the whole minute is recorded as arriving on the whole minute. Check mileage verification shall be measured from the last known mileage.
  • 23. Emergency checks are used to break tie scores, and an enduro must have at least two such checkpoints. Time is taken at an emergency check in minutes and seconds, and combined total emergency points lost are used to break tie scores. When a tie continues, the emergency check closest to the end of the meet is used to break the tie. If the tie still exists, each preceding emergency check is compared until the tie is broken. If this fails to break the tie, or if the run ended prematurely before any emergency checks were reached, then the tie scores are compared to the last legal timed check station, going from latest to earliest checks, and the first rider to score better at any check (including the last) is declared winner of the tie. If a tie still exists, duplicate points will be awarded. If duplicate points are awarded because of ties, points awarded to riders placing beneath the tied riders are based on the number of riders in that class. For example, if two riders receive second place points because of a tie, the next placing rider receives fourth place points.
  • 24. Emergency points are calculated from the 30-second mark of a rider’s due minute. (See illustration of emergency check timing.)

  • E. Scoring
  • 1. Riders are scored on a points-lost system, with zero as the best score.
  • 2. When a rider carries his own scorecard and loses it, 10 percent of the total points lost will be assessed with a minimum of one point, and any fractional points will be rounded off to the next highest whole number. The affected rider must be scored upon his request to the referee. If a rider doesn't have a score on his card and requests that the backup sheet be consulted, he may be assessed a penalty on the same basis as a lost score card.
  • 3. A rider will be penalized one point for every minute he is late leaving the starting control. Because of traffic or other conditions, final scoring may be completed at a secret check prior to the finish control.
  • 4. At a known control, a rider will be penalized one point for every minute he is late in arriving. A rider leaving a known control before his scheduled departure time will be penalized two points for each minute he is early. There is no penalty for arriving early at a known control, unless a rider is more than 15 minutes early.
  • 5. A rider will be penalized two points for the first minute he is early, five points for each additional minute early and one point for each minute late arriving at a secret or emergency check, or leaving a start or start control before the riders scheduled departure time. 
  • 6. When a tie must be broken, a rider will be penalized one emergency point for each second early or late at an emergency check
