Trainer Paul Nicholls has been “astounded” by the achievements of Kauto Star this season as the legend of the turf prepares to run in an incredible sixth Betfred Cheltenham Gold Cup.

JUDICIAL Academy and What A Tornado will battle it out for favouritism for this evening’s Kerry AgriBusiness St Leger at Limerick, but on the track there could be one or two more getting involved in what promises to be a thrilling decider.

Kauto Star is all set to seek an historic fifth successive victory in the William Hill King George VI Chase at Kempton on December 26.

Joncol will aim to add to his Grade One haul in the Guinness Gold Cup at the Punchestown festival.

Paul Nicholls’ duo Kauto Star and Denman are again set to scrap out the totesport Cheltenham Gold Cup after the latter’s magnificent return to form in the Hennessy Gold Cup at Newbury.
