"You got carried along on a wave of enthusiasm here, it was a great feeling, Aachen offers real Championship conditions. I am delighted about the victory, we are having a great phase at the moment, our third child has just been born," said an elated "Dibo", who finished on a score of 45.1 to claim the €32,000 prize.

Second place went to Ingrid Klimke with a score of 46.70, who had a sensational ride in the cross-country with her Hanoverian gelding. "Braxxi is simply a top, reliable horse, he cantered that fast that I was even able to slow the pace down, where necessary," said Ingrid Klimke, who was very busy at the CHIO: She competed in the dressage tour with the stud stallion Damon Hill and in the eventing with FRH Butts Abraxxas.

There was bad luck for Bettina Hoy, who was clearly in the lead after the dressage and jumping. Her 18-year-old grey gelding, Ringwood Cockatoo, refused at a narrow fence on the cross-country track and slid down to 17th place.
