History was made in the 2019 Grand National as Tiger Roll became the first horse since the great Red Rum to defend his crown.

William Hill Radio's Mark Walton and John O'Connell reflect on the remarkable achievement and take a look back at some of the highlights from a tremendous three days at Aintree. 

Attention then turns to Monday's action, with John offering his selections at Kelso and Windsor. 

Join Mark Walton, Tom Morley and Will Hayler on William Hill Racing Radio from 1.50pm for all the action.

Enjoy.
