Apparently, the trainer felt a lot of pressure to please the many children who sent him encouragement and dreaming of a big win for their idol, Equinox.  To me, it was easily the performance of the day.

“You know many children have written to me hoping that the horse will win.” Kimura said. “I feel a sense of responsibility. Many fans want to see this horse do well.”

Cool little article.  Will it be the Arc where the ground might turn up too soft or the BC Turf which is sure to provide the kind of ground Equinox prefers.
