Heading to the 150th Kentucky Derby?

If so, you might have a few questions about historic Churchill Downs and the Kentucky Derby, the longest continually held sporting event in the United States.

To help you prepare for your time at the racetrack, we asked Kevin Kerstein, publicity manager for Churchill Downs, to break down some of the most frequently asked questions people have about horse racing.

What is the Winner's Circle at Churchill Downs?

The Winner's Circle at Churchill Downs is the ornately decorated area of the infield where the Kentucky Derby trophy is presented to the winning owner, trainer and jockey after the "greatest two minutes in sports."

"It originally was a small area outlined in chalk where the winners were presented their prize," Kerstein said.

Today, the horseshoe-shaped spot is hallowed ground only used once a year on Kentucky Derby Day.
