I don't know about the 8th Thursday at Santa Anita. I'm in Louisville. I might be able to give you a tip or two on the Kentucky Derby. Here's some study material for you http://www.kentuckyderby.com/ .

And there are no guarantees. There likely will be 20 colts/fillies/geldings running in the Derby this year. Good luck if you try to pick the winner.
