Kauto Star worked hard for his Haydock victory
Kauto Star's bid for a record fourth straight King George VI Chase win at Kempton on Boxing Day should go ahead despite wintry weather forecasts.
The dual Cheltenham Gold Cup winner would beat the record of Desert Orchid if he landed the 2009 race.
And course officials will lay out frost mats to insulate the track against freezing weather conditions.
"I'm very optimistic the King George will go ahead," clerk of the course Brian Clifford told BBC Sport.
The great galloping grey Desert Orchid won the three-mile festive steeplechase four times, but those victories came over a five-year period.
Kauto Star coasted to victory in the Kempton race in 2006, 2007 and 2008 for champion trainer Paul Nicholls and top Irish jockey Ruby Walsh.
His attempt to win a fourth consecutive running of the race has whetted the appetites of racing fans.
Clifford said the Kempton track was preparing to lay down special frost mats to protect the course, and its flat meeting went ahead as scheduled on Wednesday evening.
He said the five-day forecast indicated snow showers were likely to hit the venue at Sunbury in Surrey, but the track would take all suitable precautions.
"We were raceable on Wednesday despite temperatures dropping to -4C the previous night," he told BBC Sport.
"The King George card has not been called off in my 10 years here, although it was transferred to Sandown in 2005 while the course was redeveloped.
"The frost covers insulate the ground and we have twice managed to have fixtures during my time here despite snowfall, so I'm very optimistic."
Kauto Star won by a nose from Imperial Commander on his seasonal return in the Betfair Chase at Haydock in November.
The nine-year-old is strong favourite to triumph again at Kempton on Boxing Day.
Kauto Star and stablemate Denman are in line to have a rematch in the Cheltenham Gold Cup in March, with the pair currently on one victory each in jump racing's blue riband event.
