Career in Sport

Sir Sinclair’s athletic ability was obvious at an early age. He began his career as an impressive young athlete, placing in the Top Ten in the prestigious PAVO Cup in the Netherlands before being imported to the United States. Sir competed in the FEI Young Horse divisions, claiming the Markel/USEF Six-Year Old Championship and the Markel/USEF Five-Year-Old Reserve Championship, and represented the United States at the World Young Horse Championships in Verden, Germany. He continued moving up the levels to Prix St. Georges and Developing Horse with scores as high as 72%. Sir successfully schooled and showed great talent for Grand Prix, but was unable to compete due to chronic Lyme disease.


Sir Sinclair’s sire, Lord Sinclair, won his Stallion Performance test, the silver medal at the World Young Dressage Horse Championships in Verden, and the German Young Horse Championships in Warendorf with top scores. He was considered a top-level dressage stallion and competed through Prix St. Georges. This incredible dressage talent was passed on to his offspring, including more than 20 Approved sons.

Sir Sinclair’s dam, Krishna, is a Star, Sport, Preferent and Prestatie mare. She is by Flemmingh, Preferent, the sire of Lingh and Krack C.
