Race Format & Scoring

Race Entry
The racer must enter by their name on their AMA card. (If your name on your AMA card is William Smith. Do not enter the race as Billy Smith.) They must also be sure to list the bike brand for contingency.

For co-sanctioned nationals, the racer must compete in their ACES class in order to be scored correctly. (Ex: If riding for ACES 50+A points, the racer must ride 50+A at the national. NOT 55+A, even if the racer meets that age requirement, as that class does not ride the whole course.)

Race Format
The series is sanctioned by the AMA and will run according to AMA traditional timekeeping enduro rules and restart format enduro rules, depending on discretion of each individual club. View the AMA Rulebook.

Row Assignments
Except for the assigned AA rows, rows will either be determined from pre-entry selection or may be randomly drawn at the discretion of the club. For racers wishing to ride together, one racer will draw for all racers. If the row is not empty, the closest empty row will be assigned. Only the assigned AA racer’s slot and one additional racer slot will be reserved. It may be released if not claimed by Wednesday prior to the event. *Not applicable to national events that are co-sanctioned.

Sportsman riders will be mixed in with other rows. (Take them under your wing and teach them the ropes.)

Tech Inspection
It is the hosting club’s discretion to perform tech inspection at each event. Closed-course events do not require a headlight, taillight or license plate. At all other events, the appearance of legality is at the club’s discretion. Ultimately, it is the racer’s responsibility to follow applicable laws. All bikes are subject to AMA sound test standards. The club retains the right to refuse entry.

All tear-offs for goggles are banned at all ACES events. Violators shall be subject to penalties at the club’s discretion and may include up to be disqualified from the event. 

Scoring at the Race
If a racer is unable to finish a race, but made it to the first check, they should to turn in the scorecard to a club member BEFORE they leave the event. They could still receive points.

Once the protest period is over at the enduro, the scores for that event are final. It’s possible that mistakes happen in the key-in process with manual score cards, but after the referee calls the end of protest period — the results are finalized. It’s the racer’s responsibility to stay and make sure the score is correct. If a racer chooses to leave before the end of the protest period, that’s their choice. Scores will not be changed when the racer gets home later and realizes something has been keyed in wrong. Results cannot be changed after the protest period is over and awards have been handed out.

Where a racer finishes in a co-sanctioned, NON-national event is the place they will be given. (We will no longer be removing D14 riders to calculate “ACES-only” updated racer placings) For co-sanctioned national events, results will be combed to remove non-ACES racers. Finishes/points will be calculated for ACES racers only.

Points & Advancement

Points System
Starting in 2023, the last 4 digits of a racer’s AMA number shall be their ACES series ID (This is not a “membership,” and there is no charge. It’s simply to keep record of riders.)

Class and overall points will be calculated using the scale below.

Award Eligibility
In order to qualify for year-end awards, a racer must ride six (6) or more events to be considered for year-end awards (not including worker points). If there are 10 or more events in the series in a given year, there will be two throw-away scores. If there are less than 10, there will be one throw-away.

For 2024, there will be one (1) throw-away race – meaning the lowest event score will be thrown out at the end of the season for class points. No throw-away race for the overall points. (A racer is no longer required to work an enduro event to be eligible for awards. However, the racer is still highly encouraged to do so in order to keep the sport alive! Worker points will still be given to those that do assist.)

At the club’s discretion, a club member will receive worker points equal to their highest class and overall points for assisting the club with event preparation, including layout, trail maintenance, etc., and/or working their club’s event. Worker points will not be awarded to a racer showing up to “help” run a check. Worker points apply to both class and overall points if you are a working club member and work your event.

ACES hopes this point system will allow racers to consider joining a club without fear of forfeiting the chance of winning their class. Each club will notify the ACES Scorekeeper in advance of their event with a list of club members that have been assisting in layout and desire worker points. If a racer’s club has more than one event in a year, and the racer works to prepare for the event or works the event, the racer will earn worker points for each event.

D14 riders competing in an ACES event that pays D14 points must notify the club if they want D14 points, otherwise they will be paid ACES points only.

If a racer sees a mistake in the points listed on the website (meaning a human error in the input after the race, not a protest of placement), they must notify the Scorekeeper no later than one week after the event. Any questions regarding points should be directed to: ACES Scorekeeeper

Points Scale
All classes will be calculated on the 20 point scale regardless of number of entrants.

Finish Position / Points
1st / 20
2nd / 16
3rd / 13
4th / 11
5th / 10
6th / 9
7th / 8
8th / 7
9th / 6
10th / 5
11th / 4
12th / 3
13th / 2
14th / 1

All ties in final points will be broken as follows:
-Rider with the most 1st place finishes.
-Then, the most 2nd place finishes if needed.
-Then, the most 3rd place finishes etc.
-If still tied, the winner of the last head to head competition will prevail.

Advancement to AA:
-ACES will advance the top 10% of the A class to AA for the coming season.
-Advancement will be based on the average A attendance for the year. ACES will always round the average up to the next whole number.

Advancement from B to A class is based off of the AMA advancement list. View the AMA advancement.

C class riders will advance as follows:
-Winning the C class for the year
-Two or more class wins
-Self-promotion to B
