Arlington Park

Arlington Park is a horse race track in the Chicago suburb of Arlington Heights, Illinois. Horse racing in the Chicago region has been a popular sport since the early days of the city in the 1830s, and at one time had more horse racing tracks (six) than any other major metropolitan area. Arlington Park was the site of the first horse race with a million-dollar purse in 1981.

The track has a one mile and one-eighth dirt oval and a one mile turf oval. The track is capable of seating at least 50,000 with extension. There is stabling on the backstretch for over 2,000 horses.

Arlington Park is replacing the dirt course with a synthetic track, to be in place for the opening of 2007 season in May.
