Charlotte Dujardin admitted an error-strewn outing in the team dressage event was what propelled to defend her individual European grand prix special title in Germany.
The 30-year-old and her horse Valegro scored a superb 87.577 per cent – just short of their world-record score of 88.022.
The special test is an event in its own right but also a qualifier for Sunday's showpiece freestyle test, set to music.
The pair had helped Great Britain to team silver on Friday behind the Netherlands, but after being less than impressed with her outing Dujardin insisted it was a relief to get back to her best.
"On Thursday, I think I was maybe a little too laid back and just rode for a clear round," said Dujardin, whose gold medal triumph came in front of a 30,000-strong crowd at Aachen's main stadium.
"But today, because of my mistakes on Thursday, I thought 'right, I'm sick of this,' and I wanted to go in and better my performance as I know Valegro can do much better than that.
“Today, he felt on great form and I knew I just had to go in and ride him. I had a good ride from start to finish.
"It's tough with a German crowd. They really get behind their riders - a bit like we had in London - and coming here and doing it is amazing.
"It's tough, but I have to remember that this is my passion and what I love, and that's how I keep the nerves from kicking in. I know I have to go in there, nail it and do my best, but today I really did enjoy it."
