HOUSTON (AP) _ Former U.S. Olympian Leonard Hilton, a world record-holder while at the University of Houston, died Tuesday after a battle with pancreatic cancer. He was 52.

Originally from Hillsboro, Texas, Hilton lettered at Houston from 1967-71 and was the anchor of the Cougars' relay team that set a world record in the indoor distance medley relay in 1970.

Hilton made the 1972 Olympic team in the 5,000 meters.

A U.S. champion in the mile in 1973 and 1975, Hilton was the first native Texan to run a sub-4-minute mile _ a feat he accomplished 32 times in official competitions.

Hilton earned his degree in engineering from Houston and later served as vice president of operations with Kinder Morgan Energy and Enron Corp. He was diagnosed with pancreatic cancer in spring of 1999.

Hilton is survived by his wife Christie, and their foster children, Elsa and Gabriella Castellon Quisbert. Funeral services will be Friday at Saint Michael's Catholic Church.
