Quarter Horse racing at Fairgrounds

The Alameda County Fairgrounds is a 270-acre (110 ha) facility located in Pleasanton, California. It is home to the annual Alameda County Fair, held since 1912,[1] as well as numerous trade shows and community events. Located on its grounds, the Pleasanton Fairgrounds Racetrack was built in 1858, making it the oldest one-mile (1.6 km) horse racing track in the United States. There is a 3,000 seat amphitheater, as well as a 9-hole golf course located within the track's infield.

The Alameda County Central Railroad Society has maintained a model train exhibit at the fairgrounds since 1959, which has grown to two 15-by-100-foot (4.6 by 30.5 m) layouts in O scale and HO scale.[2]

Building J, also known as the Amador Pavilion, is a multi-purpose arena and livestock event facility at the fairgrounds.[3] It was briefly home to the Tri-Valley Ranchers of the National Indoor Football League.

Fair cancellations happened in 1917–1918, 1942–1944 and 2020.
