The Tour of California (Amgen Tour of California) is an annual professional cycling stage race on the UCI America Tour and USA Cycling Professional Tour. It began on February 19, 2006. The eight-day race covers 650–700 miles (1,045 - 1,126 km) through California. A typical edition might begin in Nevada City, travel through the redwoods, wine country and the Pacific Coast, and finish in a southern California city such as Escondido. The 2009 race crossed the Central Valley from Merced to Fresno, with an excursion through the Sierra Nevada foothills, before crossing to the coast. The tour is sponsored by Amgen, a large California-based biotech company.
