Kinetic sculpture races are organized contests of human-powered amphibious all-terrain works of art. The original cross country event, the World Championship Great Arcata To Ferndale Cross Country Kinetic Sculpture Race, now known as the Kinetic Grand Championship in Humboldt County, California, is also called the "Triathlon of the Art World" because art and engineering are combined with physical endurance during a three-day cross country race that includes sand, mud, pavement, a bay crossing, a river crossing and major hills.
Kinetic sculpture races are held in many locations:
There are other kinetic challenges, derbies and so on which follow some of the rules and traditions of kinetic sculpture racing, but are not an official part of it.
Races were formerly held in Poland, Geraldton, Western Australia,Clearlake, California and Prescott Valley, Arizona
The concept of kinetic sculpture racing originated in Ferndale, California in 1969 when local sculptor Hobart Brown "improved" the appearance of his son's tricycle by welding on two additional wheels and other embellishments. Seeing this "Pentacycle," fellow artist Jack Mays challenged him to a race. Others later joined in creating a field of twelve machines that inaugurated the first race down Ferndale's Main Street during the town's annual art festival. Neither Hobart Brown nor Mays won; instead, the first winner was Bob Brown of Eureka, California whose sculpture was a smoke-emitting Turtle that laid eggs. The race received broad publicity when photos of Congressman Don Clausen riding the Pentacycle were seen nationally.
The event was repeated in 1970, and the course subsequently expanded to include cross-country terrain. When affiliated races were initiated in other cities and the course grew, the Ferndale event became the World Championship, and has grown into the largest single event in Humboldt County.
During the 1970s, the race adopted its present three-day, cross-country format and became the "Triathlon of the Art World." Machines tackled mud, sand, water, gravel and pavement. Stan Bennett's book Crazy Contraptions chronicles the first five years of the race. In the early 1980s, Hobart Brown was referred to as the "Glorious Founder of the Kinetic Race" in a spectators' brochure.
