Since 1993, the Graand Kinetic Challenge has been the premier event of the da Vinci Days festival of Art Science and Technology that is held on the 3rd weekend of July in Corvallis, Oregon. Originally hosted on the Oregon State University Campus (with out of town teams staying at the Fairgrounds), the event is now hosted entirely at the Fairgrounds.
Their biggest test is the race itself and what a course it is! Racers must ride over 20 miles of city streets, over a man-made sand dune, through 200 feet of deep, thick, sticky mud, and down 1.6 miles of the Willamette River.
All of this under pedal power with no help from their friends (or spectators)!
