The Betfair Chase is a Grade 1 National Hunt steeplechase in Great Britain which is open to horses aged five years or older.
Its sponsor, Betfair, offered a sum of £1,000,000 to leading contenders for successful performances in two subsequent races.
The Lexus Chase was included as an alternative second leg for the next two years, and Kauto Star won the prize by taking the original route in 2006–07.
The format was changed in 2008–09, when the bonus became available to any first-three finisher achieving first or second at the Cheltenham Festival and then winning the Grand National.
[3] Since 2016 the Kauto Star Trophy has been awarded to the owner of a horse completing the Chase Triple Crown.
