Ed Chamberlin and Francesca Cumani present live coverage of the opening day of the 2018 Cheltenham Festival. The feature race is the Champion Hurdle (3.30pm), in which last year's winner - Buveur D'Air - is a warm favourite to win once again. Chief supporting races include the traditional curtain raiser to the meeting, the Supreme Novices' Hurdle (1.30 pm), the Arkle Novices' Chase (2.10 pm), a fiercely competitive three-mile Handicap Chase (2.50 pm) and the Grade One Mares' Hurdle (4.10 pm).
