The Alameda County Fair is an annual 11-day event that showcases the various products of this California county. It also features products from the whole state. The event is organized and operated by the Alameda County Agricultural Fair Association at the Fairgrounds in Pleasanton.

The Alameda County Fair originated in 1859 as a Floral Fair. The first modern day Fair was held in 1939 and has been held annually with the exception of the war years.

As with most state fairs in California, one of the major attractions is horseracing. The fair grounds has a one-mile horse track in Pleasanton, California that feature thoroughbred and quarter horse racing. The grandstand has a capacity of 6,608 people. On live racing dates, it attracts close to 40,000 people.

The racetrack at the Alameda County Fair grounds is the oldest horseracing track in America, dating back to 1858. It is in fact, older than New York’s famous Saratoga racetrack. The sons of Spaniard Don Agustin Bernal constructed it, and wealthy horse owners shipped their horses from the east to Pleasanton for training during the winter months.
