Katie Duerrhammer spearheaded a U.S. one-two in the 3* Grand Prix at the CDI Myakka City on Thursday, April 2, 2026, at TerraNova Equestrian Center. The 2022 World Equestrian Games team rider headed up the class with a personal best of 70.174% on Kylee Lourie’s Vividus QRE who, at 11 years old, was the youngest horse in the starting line-up of 19.

Taking Over from Dufour

Vividus QRE was acquired for Duerrhammer by Lourie in December 2024 and they contested two CDIs in 2025. The attractive gelding was formerly competed by the Danish Olympian Catherine Laudrup-Dufour. She trained and showed him up to grand prix, competing him in one CDI at small tour level and three CDI's at Grand Prix level in Scandinavia (Herning, Aalborg, Falsterbo) in the spring of 2024.

Taking on the ride on a horse already trained to grand prix level comes with its own particular set of challenges, something Duerrhammer acknowledged.

“When we purchased him, he was still very, very green at the level,” she explained. “[Taking on a made horse] is just as hard as training your own, and I’ve done both. When you have to get to know someone else’s horse language and their way of doing things, it always takes a year or two to really mesh with the horse. You can’t really expect it to go any faster and allowing that time to get strength and consistency in your own system brings you together better as a team. We’re really meshing now.”

Third CDI, First Win

Second placed Kasey Perry Glass on Heartbeat WP

Duerrhammer and the Swedish Warmblood (by Zaladin MI x Don Charly x Martini) were contesting their third CDI together, debuting at Myakka City in March 2025 almost a year ago, and riding the CDI Ocala two weeks later. They bypassed the entire international circuit at the 2026 Global Dressage Festival in Wellington, just showing in national tests to return back to the CDI ring at the lower-pressure event at TerraNova.

The victory in the Grand Prix today marked their first international win and their first plus-70% score. The high mark of 73.261% came from the E judge, Janet Foy (USA).

“Him being the youngest one in my class and coming home with the win is really exciting,” enthused the 37-year-old who spends winters training with Adrienne Lyle in Wellington, Florida, and summers in Colorado. “I attribute a lot of this success to his previous training with Catherine, and to my trainer and long-time friend, Adrienne. She is brilliant."

“I was really proud of our trot half-passes,” continued Duerrhammer, who recorded her first international victory in four years. “Vividus has incredible scope to go sideways, but keeping everything easy and consistent is a little hard for him. He’s always a maximum effort kind of horse, so one of the highlights in our entire ride was our consistency and showing a more relaxed way of going. There are lots of things to still improve, like consistency of frame and contact, but I’m super happy with his progress.”

Top Three

U.S. Olympic team bronze medalist Kasey Perry-Glass finished second, just 0.7 percentage points adrift, with 69.413% on Diane Perry’s 14-year-old Charmeur x Ferro gelding, Heartbeat WP. The Paris 2024 Olympic combination of Camille Carier Bergeron (CAN) and Finnländerin, her family’s 16-year-old Fidertanz x Donnerhall mare rounded out the podium with 69.217%.

Carier Bergeron added to her collection of ribbons on another of her family’s horses on Thursday, topping the CDI1* Prix St. Georges on the nine-year-old Vitalis x Donnerhall mare, MSJ Valentina Roma. She steered the British-bred Oldenburg to 69.706%, with two judges awarding over 70%.
