“Today, Satchmo had the right mixture of power and relaxation,” said Isabell, who was last to go into the arena.
Denmark’s Nathalie zu Sayn-Wittgenstein and Digby were the ones to beat with a personal-best freestyle score of 80.05%, delighting the home crowds — at one point, the commentator had to request that they settle down.
But, after being beaten by Nathalie the previous day in the grand prix, Isabell clinched her victory with 81.1%.
This left Nathalie in second spot, with the Netherlands’ Hans Peter Minderhoud third with IPS Tango.
British dressage rider Anna Ross Davies rode the Bowles family’s Pegasus MK for 68.45% and 12th place.
The second leg of the series takes place in Lyon, France, on Friday (29 October).
