Derby preview

At Churchill Downs they are not only putting on the final touches for the queen's arrival, but also on the race track. ABC's Jeremy Hubbard has a preview of this years Run for the Roses.

For horse racing fans, it's the most exciting two minutes of the year.

"The Derby is the special race of the year," said John Shirreffs, horse trainer.

With 20 horses running for the million dollar top prize, the Kentucky Derby is the equine equivalent of the Superbowl. But at this year's Kentucky Derby, horse racing royalty may take a backseat to British royalty. Queen Elizabeth will be joining the fans.

Also planned for this year at Derby is an emotional tribute to Barbaro, winner of last year's Derby. Barbaro captured the hearts of horse lovers when he fractured a leg at the Preakness, just two weeks after the Derby and for many a real shot at the elusive Triple Crown. After surgery and months of rehab failed Barbaro was euthanized in January 2007.

Sentiment this year is on Storm in May's side. He's blind in one eye from an injury suffered days after birth making a considered a long shot. Odds-makers give the colt Curlin a slight edge.

"He breathes nicely. I feel very good about how comfortable he is over the racetrack, over the surface. His state of mind's been very consistent, and he seems very happy to be here," said Steve Asmussen Curlin's trainer.

But Trainer Todd Pletcher hopes the odds are in his favor. He has five horses competing.

"Each one of these horses is getting just as much attention as the next, and we're trying just as hard with each one as we are the other ones," said Pletcher.

In the days before the Derby excited fans have already started racing with everything from boats to beds. It is fanfare leading up to one of the shortest events in professional sports with one of the longest histories.
