The U.S. will also be represented by two members of the U.S. team from the 2010 Alltech FEI World Equestrian Games (WEG), Reich and Sleeper. Reich, the only U.S. rider to complete the WEG course, will ride her new partner Pandor. The 12-year-old Arabian gelding has finished in the top 10 in all CEI outings in the last three years. Sleeper will ride her homebred mare, Syrocco Cadence, an eight-year-old Arabian. The pair most recently finished second at the Asheville CEI3* 160km.
Crandell and Heraldic, a 13-year-old Arabian gelding, are veteran partners having been the first pair in history to win the endurance "Triple Crown" crossing the finish line first at the Old Dominion 100, Tevis and the AERC Championship 100 in 2006. In 2010, the pair took two legs of the "Triple Crown" winning at the Old Dominion 100 and at Tevis. This will be Crandell's second time representing the U.S., having ridden on the U.S. team at the 2008 FEI World Endurance Championship in Malaysia.
Rounding out the U.S. team is Blittersdorf and Synthetic. Partners since 2003, Blittersdorf and Synthetic began competing in CEI events in 2008 and have consistently finished in the top 10.
