But after wins in her Breeders Crown heat and semi final, Led Suitcase is all of a sudden a major player in Sunday's $311,000 Group 1 2YO Fillies Final (2240m) at Melton's Tabcorp Park.
Especially after drawing barrier five - which will become four if emergency Jo Louleonie doesn't gain a start - with raging favourite Lady Belladonna to start from the second row.
"We only purchased her four or five starts ago and she had won a race before we got her, so she's always had the ability, but thankfully for us she's fitted right in here," Miles said.
"Our stable environment obviously agrees with her and she's taken that next step."
The latest being a strong 2:00.5 semi final win last Friday night when she faced the breeze for the final 800m but still proved too strong despite being sent out a $25 chance.
Miles has the utmost respect for Lady Belladonna, who cruised home by 12 metres in 1:59.3 in the other semi, but said the draw gives the favourite's rivals their chance in a race that hasn't been kind to punters in recent years.
Staccato paid upward of $30 when she won in 2007, while Keppel Bay ($8) denied hot favourite Ananz in last year's decider.
"She's not blessed with a great deal of speed, but at least she's away from the pegs and hopefully she can slot in somewhere and get her chance," Miles said.
"Barring any incidents I really think she can run in the money, but I'll be more than happy if we can be the next one to upset the favourite."
Led Suitcase isn't the only runner for Miles, who trains in partnership with husband David.
The duo, who have experienced a red-letter season, have two hopes in the $170,000 Group 1 3YO Colts and Geldings Final - Staghorn Flat (barrier 10) and Villagem (13) - while Aftanoondelite (13) will carry the stable flag in the $93,000 Group 1 3YO Trotters Final.
"We've had a fantastic season, that's for sure, and we're pretty happy with the team we've got going into next Sunday," she said.
