Winchester Speedway is a half-mile paved oval motor racetrack in White River Township, Randolph County, just outside Winchester, Indiana, approximately 90 miles (145 km) northeast of Indianapolis. It seats 4000 spectators. It is also known as the "World's Fastest 1/2 mile".
The original half-mile clay oval was built in a cornfield by Frank Funk in 1914, and the track opened in 1916 with the name of Funk's Speedway. As owner and operator, Funk pursued a two-pronged strategy to attract spectators. First, he recognized that attendance went up as the clay banks were raised higher and higher, reaching 25 feet by 1932, and the turns were said to be banked at 45° in 1948. In 1932, the track could seat 6,000 in the grandstands, with the grounds accommodating 12,000 to 14,000.
Second, Funk tested various treatments to reduce dust and increase traction for the drivers. He started with mineral oil, then branched out into various other substances, which would result in a track "not only relatively dust free but pavement fast." This work brought the attention of highway engineers, who made the track a proving ground for roadbuilding technology.
The track's 37 degree banking is one of the steepest in motorsports, and the highest-banked active racetrack in the US. Some of the most famous racers in the world have raced at Winchester including Jeff Gordon, Tony Stewart, Ryan Newman, Sarah Fisher and William "Billy" Hutson.
The track's signature event is the Winchester 400, an annual 400-lap super late model stock car race. Former winners during the first 36 editions include: Bob Senneker (7 wins), Mike Cope (3), Mike Eddy (2), Mark Martin (2), Gary St. Amant (2), Butch Miller, Rusty Wallace, Ted Musgrave, Glenn Allen Jr., Tim Steele, Scot Walters, and Hank Parker Jr.
Since 1982, the track has hosted an annual ARCA Menards Series race, skipping only 2018. The track has hosted numerous USAC midget, sprint and USAC Silver Crown events that were televised on ESPN since the 1980s.
NASCAR Southeast Series ran 7 races at the speedway between 1992 through 1998.
