Defender Kentucky five-star winners Will Coleman and Diabolo will head up the US squad for the eventing World Championships at Aachen in August.
The US selection pathway for the Aachen 2026 eventing team is more straightforward than some others such as Britain’s – where riders have the pick of multiple events – in that the vast majority of US contenders head to Kentucky Three-Day Event for either the five-star or four-star short, so these two classes act as the major spring championship trial.
As such, the US squad includes the five-star winners in Will and Diabolo and runners-up Caroline Pamucku and HSH Blake, plus frequent team rider Phillip Dutton, who was eighth on Possante. Also included are Boyd Martin and Cooley Nutcracker (11th in the five-star) and Kentucky four-star winners Tamie Smith and Lillet 3. The four-star runner Very Dignified is one of two direct reserve mounts for Will.
There are no major surprises in the squad. Selectors obviously decided they could forgive Tamie her fall at Defender Bramham Horse Trials.
Perhaps the only real question mark is the absence of Boyd’s Commando 3 (sixth at Kentucky five-star after very good five-star form in 2025) from either the squad or reserve bench – one has to assume this smart horse is out of contention with some kind of setback. Boyd has a reserve listing for Shanroe Cooley, who was third at Longines Luhmühlen Horse Trials.
The selection of Cooley Nutcracker has a particular emotional pull because he was ridden at Paris 2024 by Liz Halliday, before her life-changing injury in a fall, and is owned by a syndicate called Liz’s Nutcrackers, which includes Liz and her mother, Debby. Liz watched the horse in action at Kentucky in April, her first return to an event since her accident.
Of interest to British fans will be the inclusion on the reserve list of Wiltshire-based Tiana Coudray with her Bramham podium finisher D’Artagnan. Should she be called up, this would be Tiana’s first championship since the 2012 London Olympics.

Fellow reserve Hallie Coon (Kapriccio) is also based in Wiltshire, while Allie Knowles (Montpellier Scais) has been competing in Britain this season as part of the development tour and sealed her reserve listing with results at Bicton Horse Trials and Bramham.
The squad includes three riders from the US’s 2022 world silver medal-winning team (Will, Tamie and Boyd), but no horses – unless Will ends up riding his old favourite Off The Record (seventh individually at the 2022 worlds), who is one of his two direct reserve horses.
It will be decided nearer the time of the World Championships which four riders from the US squad make up the eventing team and which rides as an individual.
