Humboldt County's Kinetic Grand Championship is a 3-day, 42-mile race along California's North Coast from Arcata to Ferndale. Racers compete for glory, pedaling along roads, over dunes, and even through Humboldt Bay. Their vehicles, called kinetic sculptures, are all-terrain, human-powered works of art engineered to race over road, water, mud and sand. Many are animated, with moving parts such as blinking eyes, flapping wings or fins, and heads that look around.

The Kinetic Grand Championship is held annually every Memorial Day weekend. Entire families come out to enjoy the spectacle and cheer their favorite entries. The Eureka leg of the race occurs on the second day of the event, and includes an amphibious passage in Humboldt Bay near the Adorni Center. MORE INFO: KineticGrandChampionship.com
