How do I receive the racecourse map?

Course files are released to registered competitors when pre-running opens, at the PCI Race Radios booth in Hammertown.


Do I need to wait until I arrive at the lakebed to go through tech?

We have tech locations across the country for full and pre-tech before you arrive on the lakebed to help your road to hammers be less stressful. See the list of Pre-Tech locations.

Does anyone other than the driver of record need to register for the race?

Only the Driver of Record needs to register. The co-driver does not need to register, although the co-driver does need a USAC Competition License.


How do I get my car number?

If you have not raced with us in the past 12 months, email with your top three number choices. Do not complete your registration without confirming a number to avoid scoring issues. If you previously confirmed a number, you do not need to take any action.



How do I reserve a garage (location you park your camper, trailer, race car on, and "live" out of during KOH)?

Garages were available to registered competitors through the Hammertown Portal, our internal, reservation system. For questions about Hammertown, please contact


I already created a driver profile and input a number that looked to be available, without having it confirmed. Is that okay?


No, if the number has not gone through our numbering system, that number will not be considered valid and may be assigned to another driver if they select it within the numbering protocol. If you formerly created a profile and selected a number without validation, please follow the steps to confirm your number, and note the situation on the request form.


I have heard about the first times on us Ultra4 fee-waiver program. I haven't raced KOH or an Ultra4 race before, am I eligible?

What happens if I can't get a garage spot inside Hammertown?


There are many racers that do not stay inside Hammertown. It is not a requirement to stay in Hammertown. Camping spots and tents can be coordinated anywhere on or near the lakebed.


What if the car number I want is not listed or if I'm transferring one from another driver?


If you believe you have a special situation that requires assistance pertaining to a number not listed, or to transfer a number not listed, please let us know in the form after selecting your choices from the menus.


What is the Driver's Team T-Shirt Program?


After a competitor registers, we produced and sold your custom shirt on our online store, and you receive money back for each shirt sold! More information coming for 2024 soon!
