Doncaster Mile favourite Hallowed Crown has drawn a wide barrier for the $3 million race.

Winner of the Randwick Guineas over the Doncaster course earlier this month, Hallowed Crown came up with gate 23 in the 24-horse field during Tuesday's barrier draw for the 150th edition of the famous handicap.

Japanese runners Real Impact and World Ace also have deep barriers in gates 21 and 16 respectively.

Topweight Sacred Falls, chasing his third straight Doncaster, has drawn one gate inside Real Impact.

Three-year-old Sweynesse drew best of the four emergencies in gate second while his Godolphin stablemate It's Somewhat has barrier four.

Suavito, unbeaten in two Melbourne autumn runs, has drawn the rails for trainer Nigel Blackiston.

A capacity field has accepted for the Doncaster, the richest race on the first day of The Championships at Randwick on Saturday.

Hallowed Crown remained a $4.60 Doncaster favourite in a betting market bookmakers said was unaffected by the draw.
