The 2018 “Nitto Powered By Optima Batteries” is upon us, and that means that thousands of people have been camping, racing and generally going nuts for all things off-road out in California’s Johnson Valley this week. Today’s the title event, and you can watch it from wherever right now:

If that stream doesn’t work, try .

KOH is sort of the Super Bowl of the Ultra4 Race Series. Or at least, it’s the biggest spectacle in the sport and easily one of the most spectator friendly off-road racing events all year. If you already know about Ultra4 cars, you’ve seen the 40-inch tires, screaming V8s and badass scratch-built frame bodies that get flung over rough tracks all over the world.

If you’re still getting up to speed: Ultra4 cars are like Jeeps if Jeeps took the Capitan America serum and also put on Iron Man suits. Sorry, we were talking about The Avengers last night and that got stuck in my head.

Anyway, after thrash their personal vehicles through ridiculous obstacles, we now get to see some of the most elite off-road drivers drive, scramble, winch and bash their way across hundreds of miles of rocky desert.

Coverage officially starts at 7:30 a.m. pst on Feb. 9, with the race kicking off a half hour later and most likely running into the night for most competitors. And if you’re tentatively interested in following this sport a little more closely, the event’s organizers have made up a tidy little cheat sheet with all you really need to know:

Four racers have won KOH the past eight years, demonstrating that it takes a lot more than luck to be on the top step. Will one of them win again this year, or will a new King ascend to the throne? All Kings have returned in 2018 except for 2007 winner JR Reynolds.

Past winners:

2017- Shannon Campbell

2016- Erik Miller and Robert Ruggiero

2015- Randy Slawson and Michael Slawson

2014- Loren Healy and Casey Trujillo

2013- Randy Slawson and Michael Slawson

2012- Erik Miller and Robert Ruggiero

2011- Shannon Campbell

2010- Loren Healy and Rodney Woody

2009- Jason Scherer and Jason Berger

2008- Shannon Campbell

2007- JR Reynolds and Randy Slawson

Shannon Campbell is the only driver to win KOH three times. Scherer is the only King at KOH 2017 that hasn’t won the title twice. He finished 2nd in 2016. Healy and Slawson are the only two drivers to win KOH after having to qualify through the LCQ. Only one driver has won King of the Hammers in a single-seater with independent front suspension—Shannon Campbell.
