What is the record for the most winners by a trainer in a single day?
As listed in the Guiness Book of World Records, the record number of winners trained in a single day is twelve. That was the number sent out by Michael W. Dickinson, at six different meetings across Britain, during the Bank Holiday programme on Boxing Day, 1982, and included Wayward Lad, winner of the King George VI Chase at Kempton Park. Apparently, while having dinner with his parents, Tony and Monica, in early November, Dickinson Jnr. announced, to the exasperation of his father, that he was going to break the world record for the number of winners in a day. He eventually ran twenty horses on Boxing Day, of which twelve won and just one finished outside the first three. The record is unlikely ever to be broken.
