Strike the Hammer
Each February, hundreds of rock racers compete in a 165-mile-long race through Johnson Valley in California's Mojave Desert. Many call it the toughest off-road race on the planet. Thousands of fans are watching. Adrenaline is pumping. Two trails in the race, the Jackhammer and the Sledgehammer, are the most difficult. They're known as the Twin Hammers—the place where legends are made.
