Attention all Crandon Ultra4 USA racers!

For the third time in Crandon’s 54-year history we will be hosting the entire Ultra4 USA series of racers at the famous Polaris Crandon World Championship Off-Road Races® and the 2023 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 65,000-plus people expected for this year’s event.
With the support of Ultra4 USA’s management and enthusiastic corporate partners we have worked hard to make sure that all Ultra4 USA competitors enjoy their annual visit to “The Big House.” The largest race of its kind in the world, the weekend will provide Ultra4 USA 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 1st) .
Nothing stands still at the Big House. We have added a new rock section in the famous Crandon Barn Turn to join the existing one located just after the Crandon finish line. The Ultra4 USA Off-Road Park used for Saturday night’s event now includes a new Mid-Track configuration linking the short-course track with the Off-Road Park, as well as a whoop section and a banked hairpin before the big rock sections.
Note! Crandon’s primary concern is the safety of its fans, drivers and race teams. In light of that objective, beginning at the 2023 Polaris Crandon World Championships, the track’s ownership group is mandating that no co-drivers be allowed in any Ultra4 USA vehicle in any class at any time.
Ultra4 USA and Crandon have also spent the summer creating a new combined Ultra4 USA camping and hospitality area nicknamed “Crandonland.” This new area will be organized and executed by the Ultra4 USA team that includes JT Taylor and Alan Johnson. We have upgraded the Ultra4 USA “Project X Ridge” spectator area for Saturday’s “Rage on the Rocks” night race with all Ultra 4 USA classes running in our updated UltraCross course. We will include music, a bar, two big screens and audio to watch the professional livestream broadcast, fireworks and insane night lighting. Not to mention having the 4400 group showcased as a Pro class on Sunday’s Red Bull World Cup! And, we may add some additional competitions for Sunday night as well.
While we are still finalizing all of the details, we felt it time to offer you some general notes and details regarding the event and the regulations for the weekend.
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:

  • Be prepared for all types of weather. This isn’t the west coast or Baja. Warm weather, cloudy, cold and heavy rain can all happen in one day. Prepare your teams in terms of proper clothing, and also your cars and race equipment accordingly. The dirt here at Crandon is awesome but also has a good amount of clay in it. Bring plenty of tear-offs etc. We do have a big concrete wash station on site.

  • As hard as we try to stay on schedule and get all our racers the promised track time, weather can play a big factor in the weekend. Track officials and the Champ Off-Road/Ultra4 USA series management are sticklers for being right on time if the weather permits. Please stay as flexible as possible in terms of the weekend’s timing.

  • Crandon fans are epic and enthusiastic. They want to see the cars, meet the drivers and get autographs and stickers. Just be prepared for this kind of reception.

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

  • Flights: Please explore flights into Green Bay, Appleton, Wausau or even Rhinelander. Drives through these areas are beautiful.
