Will Coleman began his riding career when he was just 6 years old, riding his Shetland Pony, TJ, in the Virginia hunt fields with family and dabbling in multiple disciplines. Coleman’s interest in eventing was cultivated when he attended a clinic with eventing greats Karen and David O’Connor and later went to work for them in the summers.

Coleman’s youth career reached a pinnacle in 2001 when he was the individual gold medalist at the North American Youth Championships. With his Irish Sport Horse, Fox In Flight, he became the first U.S. athlete to win the Bramham CCI4*-L in 2003. The pair made their CCI5*-L debut that same year with a completion at Burghley and were subsequently named to the U.S. Eventing Team short list for the 2004 Athens Olympics.

In 2012, Coleman and his Westphalian gelding Twizzel were part of the U.S. Eventing Team at the London Olympics. He had his first World Championship outing as part of the team for the 2018 FEI World Equestrian Games in Tryon, N.C. riding Tight Lines, owned by The Conair Syndicate.

Coleman made history in 2021, riding Off The Record, owned by Off The Record Syndicate LLC, to victory at the CCIO4*-S at CHIO Aachen, becoming the first American to ever win the prestigious event. The following year, the pair were part of the silver medal-winning U.S. team at the 2022 FEI Eventing World Championship in Pratoni del Vivaro, Italy. In 2022, Coleman was a USEF Equestrian of Honor and was awarded the William C. Steinkraus Trophy at the USEF Pegasus Awards.

Coleman had a stellar 2024 season with both Off the Record and new mount, Diabolo. The pair finished one-two at the competitive CCI4*-S at the Kentucky Three-Day Event. Ultimately, Coleman was selected to his second U.S. Olympic Eventing Team, opting to take Off The Record, with Diabolo as a direct reserve for the 2024 Paris Olympic Games.

Coleman and his wife Katie, a professional eventing and dressage rider, operate Will Coleman Equestrian based in Virginia and Florida.

Ariel Grald launched her international eventing career as part of the Area I team at the North American Youth Championships in 2004. In 2014, she was named to the USEF Under 25 Developing Riders List. That same year, she earned her first win at the FEI level, riding LBF Oleagh’s Image to first place in the CCI3*-S at Carolina International.

In 2014, Grald began her partnership with Leamore Master Plan, a then-five-year-old Irish Sport Horse owned by Annie Eldridge. The pair made their five-star debut together in 2019 at the Land Rover Kentucky Three-Day Event CCI5*-L, where they finished in 12th place. They went on to compete at the 2019 Land Rover Burghley Horse Trials, finishing 10th overall and as the highest-placed Burghley first timer. In 2021, Grald and “Simon” placed third at the Lumühlen CCI5*-L. In 2022, the pair won the Maryland CCI4*-S and finished 11th individually at the FEI Eventing World Championships in Pratoni, Italy.

Grald was a 2019 recipient of the Jaqueline B. Mars International Grant and was named to the USEF Development Training List in 2019 and 2020.

Boyd Martin, the son of Olympic speed skater Toy (Dorgan) Martin and Olympic cross-country skier Ross Martin, began riding at a young age in his native country of Australia. He made his debut at the CCI5*-L with a win at the 2003 Australian International Three-Day Event riding the Thoroughbred gelding True Blue Toozac.

He moved to the U.S. in 2007 to further his career as an eventing professional, serving as the assistant trainer to Olympian Phillip Dutton for two years before starting his own business. Martin began riding for the U.S. in 2009.

Martin is a three-time Olympian, having represented the U.S. in London 2012, Rio de Janeiro 2016, and Tokyo 2020. He is a four-time U.S. Eventing Team member for the FEI Eventing World Championship, including as a part of the silver medal-winning team in 2022 in Pratoni, Italy. With Pancho Villa, he was a member of the U.S. team that won gold at the 2015 Pan American Games, and in 2019, he won team and individual gold at the Pan American Games with Christine, Thomas, and Tommie Turner's Tsetserleg TSF.

Twice, Martin has been the USEF CCI5*-L Eventing National Champion at the Kentucky Three-Day Event. First in 2019 with Tsetserleg TSF and again in 2021 with Christine, Thomas, Tommie, and his own, On Cue. In October 2021, he won the inaugural Maryland 5 Star with On Cue, becoming the first American to win a CCI5* since 2008.

In 2023, Martin piloted his string to several significant top finishes at the CCI5*-L with five top-ten finishes at events around the world, including two top-ten finishes for Fedarman B at both Luhmuhlen and Pau. Martin brought both Fedarman B and Commando 3 forward as potential Olympic selections at the start of the 2024 season. A strong showing of both at the CCI4*-S at the 2024 Kentucky Three-Day Event did not make selection easy, but Martin ultimately chose Fedarman B as his mount of the 2024 Olympic Games, with Commando 3 as a direct reserve. Paris 2024 will be Martin's fourth consecutive Olympic appearance for the U.S. Olympic Eventing Team. 

Martin and his wife, professional dressage trainer and athlete, Silva Martin, own and operate Windurra USA in Pennsylvania.
