Nick Luck and the Channel 4 Racing team present all the drama and action from day two of the Grand National festival. It's Ladies Day, and the vibrancy and fun off course is matched by the quality of the action on it with four more Grade One contests worth over ú600,000 in total prize money. Today's feature is the Melling Chase won last year by Don Cossack, giving AP McCoy a memorable last Aintree success. There's also another chance to see action over the formidable National fences with the Topham Trophy, which trainer Nicky Henderson is looking to win for the fourth year in a row. Aintree: 2.15, 2.50, 3.25, 4.05 and 4.45pm. Presenters: Nick Luck and Emma Spencer, Reporters: Alice Plunkett and Mick Fitzgerald, Commentary and Analysis: Simon Holt, Richard Hoiles, Jim McGrath, Graham Cunningham, Tanya Stevenson and Brian Gleeson.
