After a night of heavy rain and thunderstorms, Churchill Downs track superintendent Butch Lehr cancelled this morning's scheduled training and it's 13-race card.
The Huffington Post has the story on this morning's cancellations and how the weather could potentially affect today's race:
Butch Lehr (LEE'-ehr) made the decision early in the morning as crowds began to line up outside the historic Louisville track. Saturday is the 138th running of the Kentucky Derby.
The main track, which is dirt, was labeled sloppy at 8 a.m. EDT. The Derby will be run at 6:24 p.m. EDT, with the National Weather Service calling for mostly cloudy skies, a high near 85 and a 50 percent chance of pop-up rain.
