Akiko Yamazaki and Four Winds Farm have announced the retirement of Suppenkasper, a staple of the U.S. Dressage Team for the past six years. Ridden by six-time Olympian Steffen Peters, Suppenkasper represented the United States at two FEI World Championships, two Olympics, an FEI Dressage World Cup Final and numerous Nations Cup competitions.

“Mopsie” earned both Olympic (Tokyo 2021) and world championship (Tryon 2018) team silver medals, and he was fourth at the 2023 FEI Dressage World Cup Final in Omaha, Nebraska. He earned the viral moniker of “Rave Horse” for his popular freestyle from Tokyo. Suppenkasper competed in more than 80 international competitions with Peters and earned 59 Grand Prix-level victories in CDI competitions throughout their career together.

“Today, I look out my window to catch Ravel and Mopsie basking in the sun, the large crowds and long airplane rides now a distant memory,” Yamazaki said in a U.S. Equestrian Federation press release announcing Mopsie’s retirement. “As we mark 20 years together as a team, the time has come to end this amazing journey, and it is with deep gratitude to Steffen, the horses and everyone that has been part of this journey that we now end this excellent adventure and long ride with this team. With Steffen as our rider, and with a number of horses, including Lombardi, Ravel, Legolas, Rosamunde and Suppenkasper, our team has traveled around the world and had the honor of representing the USA in multiple international championships and events.”

The 16-year-old Dutch Warmblood (Spielberg—Upanoeska, IPS Krack C) bred by F. van de Poel did his first international Grand Prix with Germany’s Helen Langehanenberg in 2017 before Yamazaki and Four Winds Farm purchased the gelding for Peters that July.

“What a true honor it has been to be a part of Mopsie’s career and life,” said Peters, San Diego. “It’s hard to explain how much appreciation I have for Akiko for purchasing him [seven] years ago and then supporting us to compete around the world together. The historic silver medal in Tokyo was, of course, the highlight of our career together. For me, it will always be one of the proudest moments of our partnership—to have Mopsie deliver for our team that night in Tokyo. The individual victories were amazing, but I always felt the proudest delivering for our team, and it meant the world when we accomplished that in Tokyo.

“Mopsie became the ‘Rave Horse’, that’s still special to me because he connected so many people,” he continued. “They recognize him and his accomplishments, and there’s really no reason to mention my name, but it’s Mopsie’s character and energy which made people gravitate to him. The journey we’ve shared together is quite hard to put into words, but thoughts of gratitude, thankfulness, and friendship come to mind, both for Mopsie and Akiko, and I’m so privileged to have been a part of this journey with them.”

The horse represented the U.S. at the Paris Olympic Games this summer, placing 51st in the Grand Prix.

Suppenkasper will live at Four Winds Farm in Woodside, California.
