LONDON -- American 15-year-old Katie Ledecky won the 800-meter freestyle at the London Olympics on Friday.
The youngest member of the U.S. swim team narrowly missed a world record in the grueling race, falling off pace on the last lap and finishing in 8 minutes, 14.63 seconds.
Mireia Belmonte Garcia of Spain touched in 8:18.76 to take the silver medal and defending champion Rebecca Adlington of host Britain finished in 8:20.32 for bronze.
