What is ISOC?

ISOC (The International Series of Champions) is headquartered in Albertville, MN, a Twin Cities suburb in the heart of the snowbelt. Founded in the mid-1990’s by John Daniels, ISOC has always been known as “the racers circuit”, with the best track design, safety, and racer payouts in the snowmobiling world.

Do I have to be an ISOC member to race?

In order to race an ISOC event, National or Regional, you must be a competition member. We offer an annual competition membership, a 120cc competition membership, a family competition membership, a vintage membership, and also a weekend membership (good for one weekend only – MN Regional only).

What do I get with my competition membership?

A members only hat- Membership to the AMSOIL Preferred Racer Program- ISOC sticker- National Race Highlights DVD and membership card entitling you to 10% off ISOC merchandise at the track and online.

What is the difference between the National circuit and the Regional circuits?

The National circuit is run across the country and is followed by the “Superteams” as well as Regional racers. They traverse across the country in search of the Points Championship. The Regional circuit covers the upper midwest. The regional circuits have affiliation with ISOC and offer classes from Junior to Pro level along with points championships.

How do I know which class to run?

The classes are related to age, competition level of the driver, and the type of snowmobile you are racing. Check the appropriate regional tour information page to see what classes are offered.

I’m under 18 years old. Is there anything special I need to know?

All racers under the age of 18 MUST have a completed original, notarized minor waiver form on file at the National ISOC office. Minor waiver forms can be downloaded from the website under Miscellaneous/Racer Forms. They must be completed and an ORIGINAL mailed to the office along with a copy of your birth certificate.

How do I register for a race?

Once you have become a Competition member, you may race at any of our affiliated circuits. You can register online here under the circuit you wish to run in. Log in using your assigned member ID and password and click on “Race Registration.” You may also download the entry forms (found under “Miscellaneous/Racer Forms) and fax/scan and email/mail them in. There are registration deadlines as things do fill up and a lot of pre-race prep work needs to be done. Be sure to get your entries in early. After registering, you can log into your racer profile and see what races/classes you are registered for. This will save you a phone call to be sure you are registered.

What kind of rules do I need to know?

Our rulebook is posted on our site here. You will need to download the rulebook and follow all the rules set forth in the ISOC rulebook. If you still have questions, you may email our tech director at

What about sled numbers and bib numbers?

It is the responsibility of the drivers to have clear, legible numbers that conform to the rules in the ISOC rulebook. If the numbers can’t be read while the sled is moving, you risk not being scored. Be sure to follow the guidelines in the rulebook. Bib numbers are on a first come, first serve basis. You submit three choices and we will do our best to assign you the one you have requested. There are some guidelines in choosing your bib numbers: They must be three digits. (Only pros/pro lites are allowed to run single and double digit.) No numbers starting with zero. No letters.

How does the race weekend run?

Registration: Pre-registration for your classes is required. While at the event, riders and crew check in before the event (typically the day before and morning of the event) and receive credentials to get into the facility and pit area. All riders and crew MUST sign a waiver before they are allowed on site.

Driver Meeting: There is a mandatory drivers meeting given by the race director on race days. The times will be posted on the schedule of events for the weekend.

Pre-Tech Inspection/ Practice: Before practice begins, there will be a pre-tech inspection that may include sled safety equipment and rider safety gear.

Staging: Heats will be posted on a board in the staging area as well as on our website here to let racers know which race they are in and what is being staged. If for some reason you cannot run your heat, please let the staging officials know.

Awards: Results should typically be posted within ½ hour after the race. If you have questions regarding these results, please see an ISOC official. Award presentation will be announced.

How do I advance to the next level/class?

When age permits, you may automatically advance to the next class. If a racer is dominating a class, they may be asked by the race director to advance to the next level even if the next level is above their age group (as long as insurance guidelines permit). A racer may also submit a Racer Resume (Racer Forms) and fill out a Class Advancement form (Racer Forms) one week prior to an event and request that the Race Director watch them for a particular weekend and make a decision based upon watching them race.

My kids want to race the 120 class?

If your child is racing the 120 class, a 120cc Competition Membership is required ($80). If they are also running a Transition or Junior class, they must purchase instead an Annual Competition Membership ($150). All racers under the age of 18 MUST have a completed original, notarized minor waiver form on file at the National ISOC office. Minor waiver forms can be downloaded from the website under racer forms. They must be completed and an ORIGINAL mailed to the office along with a copy of your birth certificate. An ISOC membership will not be issued until these papers are turned in. There are specific rules that govern the 120 racing. There are two divisions of 120 racing – Stock and Champ. The 120 rules are in our rulebook. A parent or guardian must attend the races and will be required to sign a different minor waiver form along with their child at racer check in.

I can’t accompany my Minor child to the race. What do I do now?

If you are unable to attend the event with your child to sign the waivers, you may fill out a Power of Attorney Form (Racer Forms), to allow someone else to sign your child in. This form must be signed and notarized prior to the event by the parents and involved parties and presented at driver check in along with identification.

I’m not a racer, but I’m a huge snocross fan. Any options for me?

We do offer a Fan Club Membership. This is not a racing membership, but it does entitle you to some of the same benefits of a competition member. Click here for more information.
