After the disappointing upset of California Chrome yesterday at Belmont by Tonalist, who did not run in either the Derby or the Preakness, Chrome's co owner Steve Coburn aired his disappointment and frustration with the media. - said Chrome and jockey Victor Espinoza had a target on their backs - Tonalist's owner took "coward's way out" - only horses who run both Derby and Preakness should be allowed to compete at Belmont - said he'll never see another Triple Crown winner unless rules are changed It has also been suggested by others that the length of time between each race should be increased, since running three races in five weeks can be hard on a horse. What do you think? Should horses have to compete in all three races instead of choosing? Should the length of time between Derby/Preakness and Preakness/Belmont be extended? Or both? I definitely think the time between races should be lengthened to give horses time to rest. As for the other, I'm not really sure. Maybe Coburn has a point, but the past Triple Crown winners faced a field that had some fresh horses, didn't they, and still won?
