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.
