Show Up in Southern California for a Show Down in the Desert

Last month, shared detailed information about equipping Side by Side/UTVs with long travel kits and upgraded suspension components. For those of you who took our advice, it’s time to put your boosted travel to the test. In less than five days, the McKenzie 250, a 33 mile course with over 15 miles of fresh terrain, takes over the quiet town of Lucerne Valley, CA.



In 1997, Southern California resident Cody Jeffers [1] initiated the Mojave Off Road Racing Enthusiasts (M.O.R.E.) to “promote competitive, safe and affordable off-road racing.” Since then, Jeffers turned his club into one of “the premier off-road racing series in Southern California.” M.O.R.E. is host to seven races each year, including the Slash X Duel in the Desert, Transaxle Engineering Challenge, McKenzie’s 250, Sierra LED 250, PCI Race Radios 300, Powder Puff Race Towards a Cure and the Jamar Championship Series Finale SNORE/MORE Rage at the River. 

With the McKenzie 250 just a few days away, thought it would be a good idea to share some insight and get our readers pumped for mid-season racing!

The McKenzie 250 is an annual race within the 105 square mile town of Lucerne Valley. Located in the San Bernardino County of California, Lucerne Valley is known as a quiet desert town with a small population and according to the Atlas Obscura [3], only two interesting landmarks. In between the heat races and awards ceremony of the McKenzie 250, spectators can take a quick trip to Jack O’Landia, an abandoned western town that most residents believe was built by a rich man with too much time on his hands. 

Even though the race is one day, there are four hours of open pre running on the preceding Friday evening. Because the track is natural terrain in the middle of the desert, it tends to change over time. Having a pre run before the race allows the drivers to get used to the track in order to prepare for the grueling and demanding five hour race day that follows. So if you can’t get there on Saturday, you can always stop by on Friday from 5-9pm to catch some pre-race action. 


If you’re more interested in entering the race rather than watching it, you can submit your information here. You must have a vehicle that follows the guidelines of the M.O.R.E. class list, a Pit Boss and designated radio frequency. Additionally, you should have the driving skills necessary to complete a 33 mile race.

The classes that are allowed to enter include 1, 3, 9, 12, 1350, 1700 and even two classes for UTVs, 1900 for production UTVs and 2900 for unlimited UTVs.
