We take a look at what the trends say since its creation in 2011.
British Champions Day has established itself as one of the iconic meetings in the Flat racing calendar since its inception in 2011. Boasting huge prize money and showcasing some of the best talent from across Europe, Saturday's six-race card is possibly the best to date.
However, with so many top-class horses going head-to-head - some at the end of long seasons, others fresh after breaks - it can prove tough to find winners on the card. We've looked back over the last five years to see if there are any trends that can point us in the right direction.
