One of the most important weekends in the Thoroughbred racing calendar is just days away, with elite racing scheduled all throughout North America and overseas as well. This is the final big weekend of Breeders’ Cup Challenge Series “Win and You’re In” qualifiers, which offer winners automatic entry in World Championships races Oct. 31-Nov. 1 at Del Mar.

As fall officially begins, the North American horse racing schedule enters the heart of the Breeders’ Cup Challenge Series, with multiple preps scheduled over the next two weeks at tracks around the U.S. Five are scheduled for this upcoming weekend, four of them held at Santa Anita Park during that track’s kickoff to its autumn meet.
