"I was (nervous) because you don't want a horse like Autumn Glow to disappoint," Chris Waller said.
"There's a massive crowd here today and it was good to see her go through her paces. She had to put up a fight. Lindermann, he dug deep and to come away that last 100 metres, it was special."
Autumn Glow became the 23rd horse to win the Group 1 King Charles III Stakes (1609m) and the Champions Mile in the same year while Waller notched his fifth win in the race stretching back to Albert The Fat in 2013.
Her record moves to 15 wins in 16 starts and earned more than $14.5 million in prizemoney James Mcdonald in the saddle for 11 of those victories.
"She was a little bit lost, at sea a bit, and even when we straightened and I gave her a click, she took about 50 metres to get going," McDonald said.
"But once she opened the shoulders up, she was never going to get rolled. She's just a brilliant specimen, a pleasure to ride, she's just so, so special."
