2022 Crandon Ultra4 World Championships

Attention all Crandon Ultra4 racers!

For the second time in Crandon’s 53-year history we will be hosting the entire Ultra4 series of racers at the famous Polaris Crandon World Championship Off-Road Races® and the 2022 Red Bull World Cup. There is nothing in off-road racing that compares with our annual Labor Day weekend World Championships, with nearly 425 race teams and 60,000-plus people expected for this year’s event.

With the support of Ultra4 management and enthusiastic corporate partners we have worked hard to make sure that all Ultra4 competitors enjoy their annual visit to “The Big House.” The largest race of its kind in the world, the weekend will provide Ultra4 teams several test sessions and two rounds of racing here at Crandon – not to mention participating in the iconic Lucas Oil Crandon Labor Day Parade (Friday, September 2nd)

Nothing stands still at the Big House, as we have been upgrading the Ultra4 “Rigid Ridge” spectator area for Saturday’s “Rage on the Rocks” night race with all five classes (three races) running in our updated UltraCross course. We will have a live band on the Vision Wheel stage, two bars, a big screen and audio to watch the professional livestream broadcast, fireworks and insane King of the Hammers-style lighting. Not to mention having the 4400 group showcased as a Pro class on Sunday’s Red Bull World Cup!

As was the case last year, we are also preparing a special new Ultra4 / Class 11 grass pit area that is an extension of the Crandon racer pits. Reservations for space and armbands can be made in the RACER section of our website at www.crandonoffroad.com.

We can’t wait to see all of you in the beautiful Northwoods of Wisconsin for Labor Day weekend.

Helpful Tips for Racing In Crandon:

Lodging: The best places to find lodging if you are not camping (which we highly recommend getting the full Crandon experience) is to find an AirBnB, or look at some towns closeby in Rhinelander, Antigo or Three Lakes/ Eagle River.

Flights: Please explore flights into Green Bay, Appleton, Wausau or even Rhinelander. Every drive through these areas are beautiful in terms of traveling to the race track.

Weather: Be prepared for all types of weather. This isn’t the west coast or Baja. Warm, cloudy, cold are all part of the Wisconsin Northwoods. Heavy rain can happen at anytime. Prepare your teams in terms of proper clothing, and also your cars and race equipment. The dirt here at Crandon is awesome but also was a good amount of clay in it. Bring plenty of tear-offs etc.

Race Car Cleaning: Please do not clean cars in the pits. Crandon provides a big concrete pad plus power washers on site at the Champion Power Wash Station. Bring your own gas for the power washers.

Schedule: As hard as we try to stay on schedule and get all our racers the promised track time, weather can play a huge, big factor in the weekend. Crandon officials and the Champ Off-Road/ISOC series work hard to stick to the published schedule if weather permits. Please stay as flexible as possible in terms of the weekend’s timing.

Crandon Fans: Crandon fans are epic and enthusiastic. They want to see the cars, meet the drivers, get autographs free and stickers. Just be prepared for this kind of reception, especially after Friday night’s feature race and into the weekend.
