It's that time of the year once more when the annual horse racing event that is the prestigious National Hunt festival in Cheltenham takes place. Tracy Piggott will be presenting live coverage of the opening day which includes the 3.30 Champion Hurdle, and races at 1.30, 2.10 and 2.50. While there will be analysis from Andrew McNamara and Donn McClean... who is NOT the fella who sung American Pie, which we swear didn't cause us any confusion. Ahem...
