It's early morning in Dubai. Meydan Racecourse is preparing for a big day culminating in the world's very richest race. And the favorite is an American horse.
Normally, there wouldn't be anything unusual about that. The race has been won by American stars like Cigar, Silver Charm and Animal Kingdom. But last year, no American contenders were in the race.
Many people believe California Chrome is the favorite because his feet are used to flying through dirt. The other horses' hooves haven't done it, nor have the horses had dirt kicked in their faces. Could they be right?
