Here, Big Brown is led to the track by one of his trainers for a workout with exercise rider Michelle Nevin. Jockey Kent Desormeaux said if Big Brown doesn't pull off the victory in the Belmont he will be disappointed. "I think anything less [than a Triple Crown] would be very devastating. It would be a crushing blow," he told ABC News' Bob Woodruff. The jockey called the Belmont "a marathon" and said, "Instead of that scintillating turn you've seen in the Kentucky Derby and the Preakness, I'd like to just let [Big Brown] start galloping on."
