Paddy Power offer just 12-1 that any horse can emulate the great Kauto Star and complete the Jockey Club chasing triple crown this season.
The racecourse group announced on Monday that once again they were offering up their £1million bonus to the successful chaser.
The treble is comprises the Betfair Chase at Haydock in November, the 32Red King George VI Chase at Kempton on Boxing Day and the newly-sponsored Magners Cheltenham Gold Cup at the Festival in March.
Might Bite, who won the King George before going out on his shield at Cheltenham in the Gold Cup, is 25-1 with the Irish firm while Native River is 33-1 to complete the treble.
Sizing John, who won the Gold Cup in 2017, and returning hero Thistlecrack are 50-1, while Haydock bully Bristol De Mai is 100-1.
Following Stradivarius’s successful landing of the £1million Weatherbys Hamilton bonus at York last month, the Jockey Club underlined that the mega windfall is once again being covered by an insurance premium funded out of the marketing budgets to promote the three Chase Triple Crown events.
Should the cheque be won it will be split between winning connections, with 65% going to the owner(s), 15% to the trainer, 10% to racing staff at the winning yard and 10% to the jockey.
“In six of the last ten years a top chaser has won two of the three legs of The Jockey Club Chase Triple Crown,” Paul Fisher, Chief Executive of Jockey Club Racecourses, said.
“We all know it would take a very special racehorse to win all three of those Grade Ones in the same season, but Kauto Star proved that it’s possible and we all remember how close Cue Card came more recently.
“I hope the challenge will prove attractive to connections this season and I look forward to the Betfair Chase, 32Red King George VI Chase and the Magners Cheltenham Gold Cup proving thrilling contests for us Jumps fans. It would be a great story for our sport if the Chase Triple Crown could be won.”
The bonus will be awarded alongside The Kauto Star Trophy, named in honour of the great chaser who achieved the feat in 2006/7.
A chaser has won two of the legs of the chase triple crown in six of the last ten seasons.
Four of those saw Cue Card in 2015-16, Silviniaco Conti in 2014-15 and Kauto Star in both 2009-10 and 2011-12 win the first two races of the challenge before failing to win the final leg at Prestbury Park.
Twice in that period the last two legs have been won by Long Run in 2010-11 and Kauto Star in 2008-9 in seasons where they did not win the Betfair Chase.
