United States Eventing Association

Entering the 25th year that the Baxter family has owned Twin Rivers Ranch, the 2025 eventing season in California’s wine country kicked off with the Twin Rivers Winter Horse Trials from Feb. 28 to March 2—the first of five USEA-recognized events to be held in Paso Robles, California, this year.

The highest level offered, Advanced, came down to the wire between Regalla ridden by Taren Hoffos and Disco Traveler ridden by Molly Duda. Hoffos and the 14-year-old Oldenburg mare (Sir Donnerhall x Rubiera) came into the final phase of show jumping on Sunday with a lead of just 0.3—with less than a second to spare—after recording the fastest cross-country round on Saturday on the course designed by Morgan Rowsell.

Hoffos and “Luna” had zero jumping penalties over the show jumping course designed by William Robertson. They added 1.2 time penalties for victory with a final score of 43.2 after Duda and “Disco” picked up penalties at two fences.

“She is just a beast,” Hoffos said about how cross-country propelled Luna and her to victory. “We know each other so well, and if I get her maybe a little too deep, she’s like, ‘No problem.’ She just hunkers down, and she’s so gritty. She’s just so honest and wants to go through the flags for me.”

Duda, the Revitavet USEA Young Rider of the Year in 2023 and 2024, and her 15-year-old Oldenburg gelding (Donatelli x Cadence) had made their debut at the Advanced level and won at this event last year. They then went East for the CCI4*-S at the Defender Kentucky Three-Day Event and competed overseas in England and Ireland as part of the U.S. Equestrian Federation European Development Tour.

They finished the year winning the CCI4*-S at the Woodside Fall International in Woodside, California, and the CCI4*-L at The Eventing Championships at Galway Downs in Temecula, California. For 2025, Duda said she hopes to return to the Kentucky CCI4*-S and make the European Development Tour.

“Disco was excellent this weekend,” Duda said. “He came out for his first event of the season feeling better than ever. I was especially proud of him in the first phase, earning a sub-30 score, which was a personal best for both of us at the Advanced level. We had a steady run on the cross-country just to get him back in the groove, and he handled all the technical combinations with ease.”

This was the first Advanced horse trials for Regalla. She made her four-star debut with Hoffos at the 2024 Twin Rivers Fall International, having won twice at three-star at Galway in 2023 and 2024. Hoffos has brought Luna up the levels from Beginner Novice starting in 2018.

“The best thing that I ever did for her was do so much at three-star and Intermediate,” she said about their 17 events before moving up. “She saw everything and all different courses and types of questions. By the time I stepped her up last September, it really didn’t feel like that big of a jump.”

Hoffos said she will point Luna to CCI4*-S competitions at Galway at the end of March and at Kentucky in April. She also credits enrolling in a program called “How to Heal” with Natalie Hummel and Hannah Sue Hollberg “about controlling your nervous system and rewriting your patterns, figuring out where your show anxiety and competition hangups and blocks are,” Hoffos said.

“I was feeling, especially after my big fall at Maryland a few years ago, that I needed some help, and it’s been a game changer for me,” Hoffos said. “I’ve been feeling so prepared and really trusting my program and instincts, and it’s really paying off with Luna. I’m seeing such good results and feeling so much better about the riding and the showing.”

Erin Grandia and Hyacinth (Contendro I x Vesper), who won the CCI3*-L at the 2024 Twin Rivers Spring International, finished third in their move-up to the Advanced level. The 10 entries at Advanced represented the most at this event since 2021.

Bon Vivant GWF and Erin Kellerhouse won the open Intermediate. They turned in one of just two double-clear cross-country rounds out of 22 at the level on the course designed by Adri Doyal. Then, they were double-clear in show jumping to win with a score of 28.8.

“I loved the courses at Twin because they are so open and gallopy,” Kellerhouse said. “Time wasn’t on my radar and just looked at my watch coming across the finish. He was super happy and confident—maybe a little too confident at the end of the course—but show jumped like a dream today.”

Kellerhouse and the 10-year-old Oldenburg gelding (Banderas x Power Point) have quite the partnership. They first competed together at the Beginner Novice level when “Pierre” was 4 years old in 2019. They won the CCI3*-S at the 2023 Twin Rivers Fall International.

“Bon Vivant had a bit of a rough last season, and we never quite got our mojo back, but I really felt like it came together this weekend,” she said. “My goal was to just go give him a positive ride and not pick at the gallop fences, which I have a tendency to do on him.”

Megan McIver and Kapitan Sparrow XII (Cador x Stutbuch) were second, and Kellerhouse also rode the third-place finisher, Ringwood Adios Amigo (Ringwood Adieu Z x Ringwood Operetta).

“It’s such a treat to have two great horses at this level that I’m so fond of,” Kellerhouse said. “The two horses couldn’t be more different. Bon Vivant is a true gentleman and will go whatever speed I want him to, and Amigo has his own ideas on things.”

Twin Rivers Ranch is scheduled to host the Twin Rivers Spring International from April 10-13, the Twin Rivers Summer H.T. from June 26-29, the Twin Rivers Fall International from Sept. 18-21, and the USEA Young Event Horse West Coast Championships & Last Chance Qualifier from Oct. 23-25.
