[15] 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.
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.
The race received broad publicity when photos of Congressman Don Clausen riding the Pentacycle were seen nationally.
Many contestants were younger than the race, having grown up with its philosophy, "Adults having fun so children will want to grow older," coined by Brown.
[24] In 2013, the annual Mother's Day Kinetic Klassic children's event moved from Ferndale to Eureka's waterfront Halverson Park.
[25] In 2014, the World Championship race course covered 42 miles (68 km), crossing a series of sand dunes, Humboldt Bay and the Eel River.
[33] In contrast to the rural flair of Humboldt County, the Baltimore race spans the city's urban center and is completed in a single day.
The 15 miles (24 km) race begins with morning opening ceremonies and the Le Mans Start down Federal Hill to AVAM on the south side of the Inner Harbor, continues past well-known sites including the Maryland Science Center, Harborplace, the USS Constellation, the National Aquarium, and Fells Point, enters the water at Canton, continues with sand and mud challenges at Patterson Park, then through Butchers Hill and downtown to the finish line at AVAM in mid- to late-afternoon.
[34] In 2002, Baltimore's race included a loop around the Patterson Park ice skating rink, a challenging extension of the all-terrain aspect.
