Breeders Cup from WikiPedia:

The Breeders' Cup World Championships is an annual series of Grade I thoroughbred horse races operated by Breeders' Cup Limited, a company formed in 1982. From its inception in 1984 through 2006, it was a single-day event; starting in 2007, it expanded to two days. The location changes each year. All sites have been in the United States, except in 1996, when the races were at the Woodbine Racetrack in Canada.

The event was created as a year-end championship for North American thoroughbred racing, and also attracts top horses from other parts of the world, especially Europe. The Breeders' Cup was founded in 1982 by John R. Gaines, a leading thoroughbred owner and breeder. Before the Breeders' Cup expanded to two days, it was generally considered to be the richest day in sports. As of 2008, the second day of the Breeders' Cup is the second-richest. In 2008, a total of $17 million was awarded on that day, down from $20 million in 2007 (two races were moved from Day 2 to Day 1). The richest single day in sports is now another Thoroughbred racing event, Dubai World Cup Night. It features six races with a combined purse of $21 million in 2008.
