In the freestyle, the dressage free program, the 45-year-old hoped to be able to lift the strengths of Blue Hors Zepter and make it into the top five.
By then, the duo had already won seventh place in Thursday's short grand prix program.
And the start was very strong.
But in the gallop there were some costly mistakes and in the end the crew landed at 76.725 percent.
- I wanted to top a little today and I did not need that.
I had a few misses in the gallop and of course it pulls down a lot.
If I wanted to be among the top five, I would have had to ride flawlessly and I did not, says Kittel, who finished in eighth place with 76.725 percent.
Jessica von Bredow-Werndl won in front of the home crowd in Germany with a percentage of 90,836.
Cathrine Dufour, Denmark, cow second and Isabell Werth, Germany, came third.
- It was very emotional.
The feeling is incredible, I have a hard time finding the words, says an emotional von Bredow-Werndl who pays tribute to his horse TSF Dalera BB.
- When I finished, she was incredible, as usual, today it was very special.
The atmosphere was actually quite difficult, but she was very focused, von Bredow-Werndl told SVT.
