It's a big weekend of racing and Derby hero, Masar, bids to follow his Epsom success in the Eclipse at Sandown. 

Sir Anthony McCoy and Ross Brierley join Mark Walton to look ahead to the Group One feature, along with the Lancashire Oaks and Old Newton Cup over at Haydock.

Join Steven Powell, James Millman and Andy Gibson on Racing Radio from 12.10pm for all of the action.

Enjoy.
