Kathleen Genevieve Ledecky (//; Czech pronunciation: [ˈlɛdɛtskiː]; born March 17, 1997) is an American competitive swimmer. She has won five Olympic gold medals and 14 world championship gold medals, the most in history for a female swimmer. She is the current world-record holder in the women's 400-, 800-, and 1500-meter freestyle (long course). She also holds the fastest-ever times in the women's 500-, 1000-, and 1650-yard freestyle events.
In her international debut at the 2012 London Olympic Games as a 15-year-old, Ledecky unexpectedly won the gold medal in the women's 800-metre freestyle. Four years later, she left Rio de Janeiro as the most decorated female athlete of the 2016 Olympic Games with four gold medals, one silver medal, and two world records. In total, she has won 31 medals (27 golds, three silvers, and one bronze) in major international competitions, spanning the Summer Olympics, World Championships, and Pan Pacific Championships. During her career, she has broken fourteen world records.
Ledecky's success has earned her Swimming World's World Swimmer of the Year in 2013, 2014, 2015, and 2016. Ledecky was also named Associated Press Female Athlete of the Year in 2017, international female Champion of Champions by L'Équipe in 2014 and 2017, United States Olympic Committee Female Athlete of the Year in 2013, 2016 and 2017, and Sportswoman of the Year by the Women's Sports Foundation in 2017. Ledecky's 10 individual gold medals at the World Aquatics Championships and 14 combined individual titles at the Olympics and World Aquatics Championships are records in women's swimming.
Ledecky was born in Washington, D.C., the daughter of Mary Gen (Hagan) and David Ledecky. Her paternal grandfather, Jaromír Ledecký, was Czech, and came to the United States from Czechoslovakia in 1947, while her paternal grandmother is Jewish. Her mother is of Irish descent. Ledecky is a Catholic and often prays the Hail Mary before a race.
Ledecky began swimming at the age of six, due to the influence of her older brother, Michael, and her mother, who swam for the University of New Mexico. Ledecky resides in Bethesda, Maryland, where she attended Little Flower School and then graduated from Stone Ridge School of the Sacred Heart in 2015. During her high school swimming career, Ledecky twice set the American and US Open record in the 500-yard freestyle and twice set the national, high-school record in the 200-yard freestyle. Ledecky finished her high-school career as the holder of the Stone Ridge school record in every swimming event except the 100-meter breaststroke.
During the summer of 2012, she trained with the Nation's Capital Swim Club (formerly the Curl Burke Swim Club) under coach Yuri Suguiyama. Following Suguiyama's departure to coach for the University of California, Berkeley, she continued to train with the Nation's Capital Swim Club under coach Bruce Gemmell through the 2016 Olympics. During the summers prior to 2012, she swam for Palisades Swim Team in Cabin John, Maryland. Ledecky accepted an athletic scholarship to Stanford University, where she swims for coach Greg Meehan's Stanford Cardinal women's swimming team.
At the 2012 United States Olympic Trials in Omaha, Nebraska (her first senior national competition), Ledecky made the Olympic team by placing first in the 800-meter freestyle with a time of 8:19.78, which was over two seconds ahead of second-place finisher Kate Ziegler. In Omaha, Ledecky also placed third in the 400-meter freestyle (4:05.00) and ninth in the 200-meter freestyle (1:58.66). Her third-place finish in the 400-meter freestyle was the fastest time ever swum by a 15- to 16-year-old American. At 15 years, 4 months, and 10 days, she was the youngest American participant at the 2012 Olympic Games.

|800 m freestyle||8:14.63 (AR)|
At the 2012 Summer Olympics in London, Ledecky qualified to swim in the final of the 800-meter freestyle by placing third overall in the heats with a time of 8:23.84. In the final, Ledecky stunned the field, winning gold by more than four seconds, with a time of 8:14.63, the then second-fastest effort of all time just behind Rebecca Adlington's world record of 8:14.10 set in 2008. In addition, she broke Janet Evans' American record of 8:16.22 that had stood since 1989. In the final, Ledecky went out hard and, by the 200-meter mark, she had already established an almost body-length lead. Her 400-meter split was 4:04.34, a personal best for Ledecky in that distance, and would have placed fifth in the individual 400-meter freestyle. At the 750-meter mark, Ledecky was 3.42 seconds ahead of Mireia Belmonte García, and 0.31 seconds under world record pace. Ledecky won by 4.13 seconds and just missed the world record by 0.53 seconds. Her gold was the first international medal of her career, earning her the 2012 Best Female Performance of the Year and Breakout Performer of the Year at the Golden Goggle Awards.
At the 2013 US National Championships, Ledecky qualified to swim in four individual events and the 4×200-meter freestyle relay at the 2013 World Aquatics Championships in Barcelona, Spain, though she later dropped the 200-meter freestyle from her program. At the National Championships, she finished first in the 400-, 800- and 1500-meter freestyle, and second in the 200-meter freestyle.

At the 2013 World Championships, Ledecky won gold in the 400-, 800-, and 1500-meter freestyle, and in the 4×200-meter freestyle relay, and set two world records. In winning the 400 through 1500-meter titles, she became the second woman ever to win the events in a World Championships since German Hannah Stockbauer in 2003. In her first event in Barcelona, the 400-meter freestyle, Ledecky became a world champion for the first time by winning in 3:59.82, setting a new American record and becoming the second-fastest performer of all time in the event.
In her second event, Ledecky won gold in the 1500-meter freestyle in a world record time of 15:36.53, breaking the record held by compatriot Kate Ziegler by six seconds. In what was a hard-fought race with Dane Lotte Friis, Ledecky overcame Friis in the final few hundred meters after losing the lead at the 300-meter mark, which included a final 50 split of 29.47.
In her third, and first relay event of her international career, the 4×200-meter freestyle, Ledecky and teammates Shannon Vreeland, Karlee Bispo, and Missy Franklin won gold in 7:45.14. Anchor Missy Franklin overtook Australian Alicia Coutts in the last 200 meters, giving the US the gold. Ledecky provided the US with an early lead, swimming the first leg in a personal best of 1:56.32.
In her fourth and last event, the 800-meter freestyle, Ledecky won gold in a world record of 8:13.86, bettering Rebecca Adlington's world record of 8:14.10. Much like the 1500-meter freestyle, Ledecky let Lotte Friis lead most of the race, making a move at the 650-meter mark to eventually win the race by 2.46 seconds.
Ledecky scored more points than any other swimmer to earn the FINA trophy for best female swimmer of the meet.
At year's end, Ledecky was named the World Swimmer of the Year and American Swimmer of the Year by Swimming World magazine. She was also named the best female swimmer for 2013 by FINA Aquatics World magazine.

Three days later, Ledecky then broke the world record in the 800-meter freestyle with a time of 8:11.00, bettering her previous mark of 8:13.86.
At the 2014 US National Championships, the qualifying meet for both the 2014 Pan Pacific Swimming Championships and the 2015 World Aquatics Championships, Ledecky finished first in the 200-, 400-, and 800-meter freestyle. In the 400-meter freestyle, Ledecky set her third world record of the year by breaking Federica Pellegrini's 2009 world record of 3:59.15 with a time of 3:58.86. With her mark in the 400, Ledecky became the first female since Janet Evans to hold world records simultaneously in the 400-, 800-, and 1500-meter freestyles.

The next day, Ledecky added her third meet record by swimming on the American 4×200-meter freestyle relay team with Shannon Vreeland, Missy Franklin, and Leah Smith. Swimming the anchor leg, Ledecky erased a 1.2-second deficit going into the final leg of the race, passing Australia's Melanie Schlanger with a 1:54.36 split over the final 200 meters. She also swam in the 100-meter freestyle heats.

Ledecky lapped three competitors in the final and finished 27.33 seconds ahead of silver medalist Boyle. National Team Director Frank Busch described Ledecky's 1500 performance as "the most impressive race I have ever seen, and I've been in the sport for 50 years.... She's blazing a completely different trail than anyone who has come before."
During the championships' closing ceremonies, Ledecky was named the female swimmer of the meet.

In the end, Ledecky was able to hold off a fast charging Pellegrini, eventually winning by a 0.16 margin.
