LOUISVILLE, Ky. – It was 2013 and Sheikh Mohammed bin Rashid al Maktoum, ruler of Dubai, would-be ruler of the racing world, had arranged a meeting with Charlie Appleby. Appleby, when he was employed by the English trainer David Loder, got involved with Sheikh Mohammed’s racing operation in 1998 and had worked inside it since, rising to become a head lad, then an assistant trainer, and now Sheikh Mohammed was opening the doors to a dream job – head trainer for Godolphin, one of the most ambitious and successful racing operations ever.
