King of the Hammers is considered the toughest one-day off road race in the world. It is the largest off-road race event in North America in terms of both competitors and spectators. It combines desert racing and rock crawling, and has expanded from one race to a series of 5 races held throughout the week and takes place each February in Johnson Valley, CA. Over 130 racers and teams assembled in Johnson Valley to do battle in the desert and race for the coveted title of "King" through some of the most difficult rock trails in the world, and vast expanses of harsh desert. With 160 miles between them and the checkered flag, the competition will be fierce.
