Of course, the fastest horse of the week ran on Derby Day, but was it the Derby winner? It was not! T O Elvis swooped in from Japan to take that honor, winning the Grade I Churchill Downs Stakes on the Derby undercard with a Beyer Speed Figure of 108. The fastest horse is presented by WinStar, home to Into Mischief's fastest son, Life Is Good, who was represented by his first black-type winner this week.
