World records don't have much shelf life

BUDAPEST - The world championships came alive on Tuesday as Lilly King of the United States won the women's 100m breaststroke title in one of three record-setting swims at the end of a breathtaking evening session.

Adam Peaty of Britain continued his breaststroke trailblazing with his second world mark of the day to reach the 50m final and Canada's Kylie Masse produced a world-best time to win the women's 100m backstroke gold medal.

And there was more history for Katie Ledecky following her routine gold in the women's 1500m freestyle as the American claimed the 12th world title of her short career.
