Transworld (26 February 1974 – 24 June 2001) was an American-bred, Irish-trained Thoroughbred racehorse and sire. Bred in Kentucky he was sent to race in Europe after being sold for $375,000 as a yearling. His brief racing career comprised only five races between May and September 1977 but he showed himself to be a high-class staying colt with wins in the Churchill Stakes, Ulster Derby and Irish St. Leger. He returned to America his stud career and had some success as a breeding stallion. Transworld died in 2001 at the age of 27. Background Transworld was a chestnut horse with a broad white blaze and four white socks bred in Kentucky by Elmendorf Farm. As a yearling he was put up for auction and was sold for $375,000. He was sent to race in Europe where he was trained by Vincent O'Brien and competed in the colours of Simon Fraser. His sire Prince John recorded his biggest wi in the Garden State Stakes before his career was ended prematurely by injury. He became a very successful breeding stallion whose other progeny included Speak John, Stage Door Johnny, Typecast, Silent Screen and Deceit. Transworld's dam Hornpipe failed to win a race but produced several other winners including Transworld's full brother Protagonist, the American Champion two-year-old colt of 1973. She was a granddaughter of Galatea who won the 1000 Guineas and Epsom Oaks in 1939. Racing career 1977: three-year-old season Transworld was unraced as juvenile in 1976 and made his debut in the Group 2 Gallinule Stakes over one and a half miles at the Curragh in May 1977. He showed some promise but finished unplaced behind his stablemate Alleged. In June he was sent to Ascot Racecourse in England for the Churchill Stakes, which was run over one and a half miles on the Saturday following the Royal Ascot meeting. He started favourite and overcame some difficulties in running before pulling away and winning by four lengths from the Guy Harwood-trained Mallard Song. Later that month he was sent to Down Royal in Northern Ireland and recorded a very easy wi in the Ulster Derby. In August at the Curragh he attempted to win his third consecutive race in the Blandford Stakes but was beaten a length into second by the Dermot Weld-trained Panamint with the filly Sassabunda in third. In the Irish St. Leger at the Curragh on 17 September
