Katie Ledecky shatters own 1,500-meter world record again

The 18-year-old won gold by 14.66 seconds at the FINA World Championships in Kazan,

Katie Ledecky shattered another one of her world records by swimming 15:25.48 for the 1,500-meter freestyle en route to gold at the FINA World Championships in Kazan, Russia. She bettered her own world record of 15:27.71 from Monday's semifinal round.

Ledecky won the race by 14.66 seconds over silver medalist Lauren Boyle of New Zealand in 15:50.15, which would have been the world record before Ledecky's rise in 2012. Hungarian Boglarka Kapas took bronze in 15:47.09.

​Ledecky's new world record is also 24 seconds faster than the men's qualifying time of 15:49.99 for the 2016 U.S. Olympic Trials.

In other Kazan competition, Ryan Lochte finished fourth in the 200-meter freestyle and Missy Franklin finished fifth in the 100-meter backstroke.

Ledecky returned to the pool just 30 minutes later to swim the 200-meter freestyle semifinal, where she finished third in 1:56.76. Ledecky was in last place with 100-meters to go before kicking the final 50-meters in 30.25 seconds. Missy Franklin won the heat, and both Americans will advance to the final. Ledecky just barely made the final by .25 seconds.
