Super mare Autumn Glow will get the chance to crown her magnificent season in the Group 1 $5 million Queen Elizabeth Stakes (2000m) at Royal Randwick next month.

Trainer Chris Waller and owner John Messara announced on Tuesday that Autumn Glow will be asked to stretch her brilliance out to a middle distance for the first time during her unbeaten 11-start career for the Queen Elizabeth Stakes on April 11, Day Two of The Championships.

This means Autumn Glow won't contest the Group 1 $4m Doncaster Mile (1600m) at the same track a week earlier.

Waller, Messara and champion jockey James McDonald discussed the various race options on Monday before reaching a consensus to aim the mare at the Queen Elizabeth Stakes.

Autumn Glow produced a career-best performance to win the George Ryder Stakes last Saturday, scoring by nearly three lengths easing down.

She returned a Timeform rating of 128, equal with The Everest winner Ka Ying Rising as the highest figure on an Australian racetrack this season, and convinced her trainer, owner and jockey that the 2000m of the Queen Elizabeth Stakes is within her reach.

"We've been very pleased with how she's come through her impressive George Ryder Stakes victory," Waller said.

"James McDonald and I have been particularly taken with her ability to relax in her races, along with her outstanding recovery post run."

Messara said Autumn Glow's virtuoso performance in the Ryder also convinced him to go to the Queen Elizabeth Stakes.

"I felt her win last Saturday was so dominant, she deserves the opportunity to go to 2000m - she wasn't even blowing after the race and has pulled up so well,'' Messara said.

"We looked at the Doncaster Mile carefully, it is a great race but it comes with the usual risks and a very big field.

"Plus it will be worthwhile finding out of Autumn Glow gets a strong 2000m as we have a race in the spring called the Cox Plate we want to consider.''
