ORLANDO, Fla.—Katie Ledecky’s 13-year unbeaten streak in the 800-meter freestyle is over, setting up a potential challenge from Canadian phenom Summer McIntosh at the Paris Olympics.
The 17-year-old McIntosh finished almost 6 seconds ahead of Ledecky at a sectional meet in Orlando on Thursday, becoming the second-fastest female in the history of a grueling event that Ledecky has dominated.
