SHEFFIELD, England (AP) — Liam Tancock set a world record in the 50-meter backstroke Wednesday at the British swimming championships.

Tancock finished the race in 24.47 seconds, breaking the previous mark of 24.80 set by Thomas Rupprath of Germany in July 2003 in the non-Olympic event.

"I felt good, smooth and on top of the water," said Tancock, who added he had been planning to go for the record. "I just felt I had a good time in me. I was feeling fast in training so thought, why not?"
