You've probably heard of the Indianapolis 500, but did you know that this auto race is held in a place that some people call "The Brickyard"?
The Indianapolis Motor Speedway was originally built in 1909 as a place where Indiana automobile manufacturers could test and race their new cars. In its early years, the Speedway was paved with bricks. Even though most of the bricks have now been paved over, people still call it "The Brickyard."
The Speedway was opened to the public in 1911 for the Indy 500, a world-famous automobile race that has taken place there almost every year since then. More than 300,000 people come out to watch the race, making it the biggest single-day sports event in the world. The track is 2.5 miles around. The race itself is 500 miles long, however, so the cars have to make 200 laps around the track to complete the race.
