One of the United States’ most prominent competition horse owners, Jane Clark, is resigning as president and CEO of the U.S. Equestrian Team Foundation after revealing that British team gold medalist Ben Maher will ride her top show jumpers.

Clark’s horses have been resting since Mario Deslauriers, who started working for her in 2009, lost the ride on them this summer. Maher has begun riding them, but they won't start competing again until the 2013 Florida circuit.
