There are a number of classes offered in Idaho City 100. Deciding on the class you should enter can be confusing. The most common mistake in deciding which class to enter is letting your ego get in the way of making a good decision. Try to keep the following in mind when choosing your class:
This is a national-caliber event designed to test a rider's ability. It is not intended to be for beginner riders and is not structured to support Electronic Bikes at this time.
It is not unusual for a large number of riders to DNF (Did Not Finish) because they don't make it to the checks on time.
When you get tired, you start to make mistakes. Mistakes lead to crashes. Crashes lead to injurys.
One of the most important parts of this event is adhering to your assigned Time Schedule. Time Schedules are structured such that the most skilled riders are given the least amount of time to complete the course while the least skilled riders are given the most amount of time to complete the course. There are typically 3-time schedules in the Idaho City 100 which are directly related to the rider skill levels.
Your score will be based on completing the course in the time allotted. You will be penalized for going thru a check early and you will be penalized for going thru a check late. The person with the least score (penalty points), wins.
The Idaho City 100 uses 4 Skill Level identifiers. Each Skill Level is directly tied to a Time Schedules. The Skill Levels are as follows:
AA - National Level Expert Riders
A - Local Expert Riders
B - Intermediate Level Riders
C - Short Course Riders
Combining Skill Levels and Time Schedules:
The AA and A Clases may run the same time schedule. The overall event winner is considered from the fastest time schedule.
B Classes are given more time to complete the course than the AA and A classes.
C Classes are given the most time to complete the course and they run a shorter version of the course as well.

No Electric Bikes at this time.
A good muffler with a spark arrestor securely attached. If you lose it, you will be required to replace it at the next checkpoint. The static dba test will require a maximum limit of 96 dba at 20 inches. (RULE WILL BE ENFORCED) Mufflers may be repaired at any time check. Spark arrestors ARE required.
An Idaho off-road sticker is required.
The machine will be impounded by the organizers. Each rider may claim their machine ten minutes before the scheduled time of departure. The rider cannot start their machine in the work area. The rider can work on their machine in the work area.
Riders are allowed to change parts in the work area and at each time check between the white and yellow flags. Tubes can be replaced at any time. Tires may be changed only at the final check of the day.
Within one minute of the starting signal having been given, the rider must have started the engine and crossed another line 20 meters from the start. A rider not crossing the 20-meter line within one minute will be penalized by 20 points. Riders arriving more than one minute late at the starting line will be penalized by 60 points per minute. The minute in which the rider arrives at the start line will be
considered as the new start time.
Putting gas and oil into your motorcycle is only allowed at each time check between the white and yellow flags. Gasoline only will be allowed just beyond the time check. You must bring the gas to the bike. You cannot ride back to flags.
A time check will be indicated by white flags 60 yards before the time-line. The yellow flag is the time-line. The clock will be located within a viewable distance beyond the time-line. A rider cannot cross this time-line with their machine until their time due appears on the time clock. If a rider does pass the yellow flag with their bike, they cannot go back and must proceed into the check for time recording. The rider may be disqualified if they are identified going in the reverse direction on the course or in the time check area.
Think of the interval between each checkpoint as a separate little “test.” Arriving late (or early) at any one of the course checkpoints does not require you to adjust your “interval time” for subsequent checks. If you arrive early or late from your due time at a check you will need to adjust the time you are due at subsequent checks, but NOT the interval.
It is the responsibility of the rider to know when they were due at any check point. The organizer will provide the time schedule prior to the start of each day. The time schedule between each time check is a separate test. If you are late at any time check you DO NOT have to make this time up. Doing so will only make you early at the next time check. The time at which you go through any check sets the start time for the next interval to the next check.
Example: Check # Original Time Due: Time In: Points:
1 9:42 9:42 0
2 10:25 10:27 120
3 11:09 11:11 0
You were on time at check #1, but two minutes late at check #2. By being late you now have a new “start time” for the next interval. You will need to adjust your original time due at subsequent checks by two minutes to stay on time. If you had gone into check #3 at your original due time you would have been penalized 120 points for being two minutes early. Always maintain the interval.
Hour out rule: You can never be more than one hour past your ORIGINAL time due at any check or you will be disqualified.
Hint: If you are really running late (like more than 30 minutes) then roll through the checks as soon as you arrive to make up time if possible. If you are that late you are already on bronze level, so early points really don’t matter that much, but going over your hour will.
These tests are the most critical measurement in an event. The basic outline for a special test is that it should be “not too difficult and not dangerous …. forbidden to practice, and specially prepared for the purpose.” It should be ridden as fast as you can successfully negotiate the course.
You can walk the grass track prior to the start of the event, but you may not ride (not even a bicycle) on any portion of the course—including the special tests—prior to the start.
If your machine is running correctly, do the basics keeping an eye on the time and go through the check when your time is up.
If you are now on a bronze level, which means more than approximately 20 minutes late on your score, you can use the one-hour late rule and work on your bike. BUT, push in no later than 59 minutes past your original scheduled time, not 59 minutes from your arrival at this final check.
You are disqualified if you are 60 minutes late from your original scheduled time at any check.
Early/Late arrival at a time check = 60 points per minute
Special Tests = One point for every second in the test
Starting later than the originally scheduled time = 60 points per minute late
Stopping between the yellow flag and check crew at time check = 60 points
The Idaho City 100 is primarily held on public lands managed by the US Forest Service and the Idaho Department of Lands. Both agencies are very concerned about the containment of fuel used in our event. The US Forest Service has regulations regarding the transportation and containment of gasoline which is a hazardous material. The Boise Ridge Riders and the Idaho City Ranger District of the Boise National Forest have agreed upon a plan for the safe transport and fueling of motorcycles with gasoline during the Idaho City 100. If you wish to participate in our event you must adhere to this policy.
As part of Technical Inspection we will check all of your gas cans. We recommend that you bring 3 gas cans to Tech Inspection. You must have all of your gas cans inspected and tagged for them to be allowed on our gas trailers. We will verify that your gas cans meet our requirements and if so, we will tag all of your gas cans. You can mark your can in any manner you desire to ease locating it at the gas stop. After we've inspected your gas cans and tagged them, you may take it with you so you can place it on the proper gas trailer. Please do not leave your gas cans on our gas trailers overnight.
Any RED gas can clearly labeled GASOLINE is an approved gasoline container. The gas can must be in good condition, structurally sound, have all it's components and not be leaking. What we mean by good condition and structurally sound is that it has all of it's caps are securely on, in place and are in good working order. In other words, duct tape, corks, screws, etc. can not be used in place of lost caps.
Gas cans can be metal or plastic. They don't need to be "heavy industrial type" gas cans.
Frequently asked Questions about our Gas Can Policy:
Do I have to use one of those "No Spill" cans? No.
Does it have to have a "Quick Stop"? No.
Can I use a "Quick Fill" can? Yes.
What if the tag comes off? You must take it back to Tech Inspection and have it re-inspected and re-tagged.
Information on our Fueling Policies and Procedures can be found below.
Approved Gas Cans image see red can picture on right above.
Containers below or others are not approved.
The Boise Ridge Riders have instituted the following policies related to the transportation of gas and fueling of your motorcycle during the event. The policies are a part of the overall requirements of our ability to obtain permits and handling of hazardous materials on public lands. Any rider that does not adhere to these policies will be immediately disqualified.
For obvious reasons, there can be NO SMOKING at the Gas Checks.

1. Have your motorcycle full of gas before you go to Tech Inspection. Upon passing Tech Inspection, your motorcycle will be taken from you by a member of the Boise Ridge Riders and Impounded. You will not get your motorcycle back until 10 minutes prior to your assigned start time.
2. Each morning that your ride, you will need to put one of your tagged gas cans on each gas trailer that goes to a Gas Check. The gas trailers will be located near Tech Inspection and Impound. Each trailer will be clearly marked as to which Gas Check it will go to. Gas cans must be placed on the Gas Trailers BEFORE YOU GO TO THE RIDER's MEETING at 8:30am each morning. The reason for this is that the time it takes for our crews to drive to the Gas Check, unload and then setup the fueling area can take several hours. Meanwhile the route the rider's take can be much shorter taking far less time. In other words, we need a head start.
3. At the end of each day you've ridden, you will need to find and remove all of the gas cans you've put on our Gas Trailers. Often times the Gas Check is in the "middle of no where" and it can take several hours to drive back to town. Our crews won't leave the Gas Check until it officially closes once the last rider goes thru. In other words, don't expect all of the Gas Trailers to be back to town until late as late as 6 or 7pm. Our crews will place a priority on dealing with lost and/or injured riders before heading back to town. So please be patient and plan accordingly. If you leave your gas can on our trailer overnight, you won't get it back - ever.
4. At the Gas Checks there will be a clearly marked fueling area with all of the gas cans in a separate, but close by, fuel containment area. All riders are required to turn their motorcycles off, push them into the fueling area, go find your gas can in the fuel containment area, take it to the fueling area, fill your motorcycle, return your gas can to the fuel containment area and then push your motorcycle out of the fueling area. We will have personnel at the Gas Checks monitoring and facilitating this process.
5. You must fuel your motorcycle on the absorbent environment matt in the fueling area, just like you would have to do at the ISDE. No exceptions. Wait your turn or be disqualified.
6. You are not required to use our Gas Trailers. Your support crew can haul your tagged gas can to the Gas Check - provided that the Gas Check is open and accessible to support crews. Your support crew, upon arrival at the Gas Check, must place your tagged gas can in the fuel containment area. You must fuel your motorcycle in the designated fueling area. At no time can your support crew place your gas can on the bare ground. If they do so, you, the rider, will be disqualified. The gas can must remain in the fuel containment area until your support crew leaves the Gas Check. Then and only then can they carry your gas can to their vehicle, place it directly into the vehicle and leave.
