More than £1million is expected to be wagered on the King George VI Chase on Boxing Day, with Kauto Star out to win the race for a fifth time.
The Nation's favourite racehorse is a four-time winner of the big race and is currently second favourite with sponsors William Hill behind reigning champions Long Run, although the firm anticipate further support for the champion trainer and jockey dream team of Paul Nicholls and Ruby Walsh between now and Monday.
William Hill spokeswoman Lucy Rhodes told Crunchsports.com: "The Nation's sweetheart Kauto Star is known for his sensational comebacks, and a familiar Boxing Day battering will have us crying into our turkey sandwiches for yet another year."
Kauto Star's stablemate, Master Minded, is third in the betting.
