The daughter of Harlan's Holiday ships into Toronto on Thursday to compete in the seven-furlong event, which has attracted a field of 10 two-year-old fillies
The Steve Klesaris trainee has only raced once, but demonstrated a great deal of potential when defeating her Delaware Park opposition by seven lengths on August 26.
Klesaris, who sent Livin Lovin to Woodbine last month to finish second in the Mazarine Stakes, said the plan was to send the Maryland-bred to New York for a September contest.
"We were targeting the Matron at Belmont. She came up with a stone bruise. We had to back up a bit," he explained. "She probably lost about 15 days of training in the middle of September."
Klesaris regrouped and opted for the Glorious Song because he wanted to try the filly over a synthetic surface.
"There's some good turf in her pedigree," he offered. "My feeling is that turf horses like the synthetic, as well. Turf horses generally like it because, much like turf, it does not break away from them. I want to see how she handles the synthetic before we go on to bigger and better things."
Holiday Girl will be ridden by Emile Ramsammy.
The Glorious Song is slated for race eight on Saturday's 10-race programme.
