The 2019 Nitto Powered by Optima battery is a spectacular off-road battle that combines technical rock crawling with high-speed desert racing. It’s going down all day Friday, which is right now, and the online livestream is free to watch and excellent.

The race officially started at 8 a.m. Pacific time, but don’t worry, the broadcast will run well into the night so there is still plenty of action to catch if you tune in right now. You should check it out. You’re probably procrastinating doing actual work anyway, right?

The video stream above will show you live coverage of the race itself along with commentary to help you understand what’s happening and who’s winning. To supplement that, you could open in another window to see exactly where everybody is on the race course.

You can also take a look at the to see how competitors started the race after qualifying, and check out if you really want to dig in.

The course is a giant snaking loop around Johnson Valley, which is a huge rocky swath of desert about 140 miles northeast of Los Angeles. Racers have to make three laps, scrambling over sand and rocks and obstacles with funny names. The whole deal is about 235 miles this year and breaks down like this:

Lap 1 - 92 mile desert loop - (high speed)

Lap 2 - 67 mile rock loop - (technical Hammers trails)

Lap 3 - 76 mile rock loop (same as lap 2 but teams must do “Sledgehammer,” “Outer Limits,” “Spooners” obstacles.)

On one of the 3 passes by “Backdoor,” teams must climb Backdoor once. This year, teams can do either “Full of Hate” (shorter, but nasty) or “Clawhammer.”

This race is about picking careful lines up ridiculous grades, strategy and even winch operating as much as it’s about flat-out speed.

The vehicles competing in this event, Ultra4 cars, are extremely robust four-wheel drive V8 buggies driven by some of the most elite rock-driving athletes in the world. The winner of today’s event gets a $100,000 payout.

A King of the Hammers race generally takes between seven and 14 hours for racers to complete, for those who do complete it. If you look at , there are a lot more DNFs than finish times.
