Will Coleman and Diabolo Secure Historic American Victory at Defender Kentucky Three-Day Event

What Happened

Will Coleman and Diabolo climbed to the top of the podium at the 2026 Defender Kentucky Three-Day Event (K3DE), finishing on a score of 28.1. Adding only 0.8 time penalties in the show jumping phase, Coleman became just the second American to win the CCI5*-L at Kentucky in the last 18 years.

The podium was rounded out by American Caroline Pamukcu, who jumped double-clear with HSH Blake to finish second (28.6), and Great Britain’s David Doel, who finished on his dressage score of 30.8 aboard Galileo Neiuwmoed to take third. Coleman’s victory also secured him the Defender/USEF CCI5*-L Eventing National Championship.

In the concurrent Cosequin® Lexington CCI4*-S, Tamie Smith claimed the title with Lillet 3, finishing as the only pair to produce a double-clear performance in that division.

Why It Matters

Coleman’s victory represents a significant milestone for U.S. eventing. Since 2008, the Kentucky CCI5*-L has been largely dominated by international riders, with Tamie Smith’s 2023 win being the only other American triumph in nearly two decades. Coleman and Diabolo also set a unique record as the first pair to win both the CCI4*-S (which they won in 2024) and the CCI5*-L at this venue.

For the broader U.S. community, the results highlight the rising depth of domestic talent. Caroline Pamukcu’s second-place finish with HSH Blake, a horse she has developed since he was a young horse, underscores the success of long-term American horse development programs. Additionally, the event served as a critical selection and proving ground for international championship contention.

Discipline Context

As one of only seven five-star events globally, the Kentucky Three-Day Event is the pinnacle of the sport in the Americas. The 2026 edition demonstrated the high stakes of the "triathlon" format, where technical show jumping courses designed by Guilherme Jorge proved highly influential.

While the CCI5*-L remains the main attraction, the inclusion of the CCI4*-S and the Kentucky International CSI5* show jumping grand prix within the same week positions the Kentucky Horse Park as a multi-discipline hub. This format allows upper-level eventers to compete alongside world-class show jumpers, reflecting an increasing crossover in technical standards between the jumping disciplines.
