Overview
Challenger (1927–1948) was a British Thoroughbred racehorse who became a Leading sire in North America.
Background
Challenger was a bay horse bred by the British The National Stud. As a yearling, Challenger was bought for 5,000 guineas by Lord Dewar.
Racing career
At age two, Challenger made two starts, winning both the Richmond and Clearwell Stakes. Following the death of Lord Dewar, his nephew John Arthur Dewar inherited his horses and, in 1930, he sold Challenger for £10,000, the then equivalent of US$100,000, to the American racing partnership of William Brann and Robert Castle.
Registered in the United States as Challenger II, the expensive colt never fully recovered from an injury to his hocks and had no success on American racetracks. However, as a sire, he would prove to be more than worth the price Brann and Castle paid for him.
