One who was not there to do so was winning trainer Archie Watson who decided to move house instead.
“No one else could have trained this horse to win,” said the ever generous Doyle. “This for me is a dream come true.
“This is a massive one especially on this horse everyone adores him but even I doubted it would be today of all days to win this.
“My heart sank on the line when I got joined by Tommy (Eaves, Brando’s jockey).”
Her victory on 11/1 shot Trueshan was as much of a shock as the sight of the out of sorts legendary stayer Stradivarius being eased up well before the line by Frankie Dettori.
Doyle shook her whip in celebration as she passed the winning post on the Alan King-trained winner 7 1/2 lengths clear of Irish St Leger winner Search For A Song.
Doyle has had a dream season even before Saturday’s achievements.
Earlier this week she rode her 117th winner bettering her own record for wins in a season for a female jockey.
She has also secured her first Group race winner this season at Newmarket and maiden Royal Ascot victory to boot.
Doyle – whose jockey boyfriend Tom Marqunad is also stamping his mark on the flat scene – says she is delighted she is not pigeon-holed.
“I am really happy at people seeing me as a jockey not a female jockey,” she said.
