Montaly will face eight rivals as he aims to add the Doncaster Cup on Friday to his recent successes.
Andrew Balding's stayer won the Chester Cup in May and also came with a late rattle to take the Lonsdale Cup at York, for which he has a 3lb penalty.

Fun Mac, a winner in France last time out, represents Hughie Morrison, with She Is No Lady going for Ralph Beckett.
The sole three-year-old is David Elsworth's Desert Skyline, while Thomas Hobson is the only Irish representative for Willie Mullins.
Heartache and Havana Grey are the star names among nine declarations for the Wainwrights Flying Childers Stakes and have been installed as the 6/4 joint-favourites by Sky Bet.
Clive Cox's Heartache won the Queen Mary at Royal Ascot in June but suffered an injury in the Prix Robert Papin when losing her unbeaten record.
Connections are hoping the ground continues to dry out with Ryan Moore booked.
