Future Stanford swimmer Katie Ledecky put an exclamation point on a record-breaking meet at The Woodlands Senior Invitational in Shenandoah, Texas, by setting her second world record in four days on Sunday.
Ledecky, 17, who has one year of high school remaining, lowered her own world mark in the 800-meter free with an 8:11.00. Her 400s were 4:05.7 and 4:05.3. The former mark, set by Ledecky at last year's FINA World Championships in Barcelona, Spain, stood at 8:13.86.
On Thursday, Ledecky broke her own world record in the 1500-meter free. Her time of 15:34.23 lowered the former mark of 15:36.53, set by Ledecky at last year's FINA worlds, by more than two seconds.
"I knew I was swimming well, but I didn't realize until I touched how much faster I was here than in Barcelona," Ledecky said in various news reports. "I'd still a bit stunned from this whole weekend. It's a great feeling."
The 800 world mark is a bigger deal because it's an Olympic event (Ledecky won the 2012 Olympic 800 free title at age 15). The 1500 free is contested at the World Championships, but not the Olympic Games.
Ledecky appears to be in spectacular form more than one month before the Phillips 66 National Championships (Aug. 6-10) in Irvine, which serves as a selection meet for the Pan Pacific Championships in Australia later in August, and the 2015 World Championships in Kazan, Russia.
Last summer, Ledecky won gold medals in all four of her World Championships events in Barcelona, including her world records in the 800 and 1500 freestyles.
Ledecky, an Olympic gold medalist, announced her verbal commitment to Stanford in May. She will be the greatest distance swimmer to enter Stanford since Janet Evans arrived in 1988 after winning three gold medals in the Seoul Olympics. Ledecky will begin her Stanford career in 2015, one year before the 2016 Summer Olympics in Rio de Janerio.
