For the first time since 1945, the Kentucky Derby won't be held on the first Saturday in May.Instead, Triple Crown announcer Larry Collmus will call a turtle race on YouTube at 6p (CST). "I don't think I've called a race that's eight minutes long," says Collmus. "I'm going to have to drink plenty of water." The real Kentucky Derby is currently rescheduled for September. Eight Turtles will compete in the slowest race in the history of mankind.
