The Champion Hurdle is a Grade 1 National Hunt hurdle race in Great Britain which is open to horses aged four years or older. It is run on the Old Course at Cheltenham over a distance of about 2 miles and ½ furlong (2 miles and 87 yards, or 3,298 metres), and during its running there are eight hurdles to be jumped. The race is the last leg of the Triple Crown of Hurdling and is scheduled to take place each year on the opening day of the Cheltenham Festival in March. As part of a sponsorship agreement with the online gambling operator Unibet, the race is now known as the Unibet Champion Hurdle.
