Katie Hoff

On December 14, 2015, Hoff officially announced her retirement from swimming due to continuing health issues related to scar tissue from blood clots in her lungs.

In April 2014, Hoff made a comeback at the Mesa Arena Pro Series. At Nationals in Irvine, California, she was forced to withdraw due to health problems. In October it was found that she had blood clots in her lungs, which took her several months to recover from.

Beginning in 2013, Hoff took a brief hiatus from competitive swimming focus on her studies, enrolling at the University of Miami as a full-time student. However, she began training with Hurricane Aquatics club team (as a professional, she could not swim in the NCAA) at the University of Miami shortly after arriving there. Hoff competed in her first meet since the 2012 Olympic Trials on November 23–24.

At the 2012 Olympic Trials, Hoff failed to qualify for her third Olympics, finishing 20th in the preliminary runs in the 200-meter and 400-meter freestyle and 13th in the 800-meter freestyle.

At the 2011 World Aquatics Championships in Shanghai, China, Hoff won a gold medal in the 4×200-meter freestyle relay with Missy Franklin, Dagny Knutson, and Allison Schmitt, with the team finishing ahead of Australia and China. As the third leg, Hoff had a 1:57.41 split.

Hoff relocated to California, where she began training and competing with the Fullerton Aquatics Sports Team (FAST) and coach Sean Hutchison. She began to return to form, and at the 2010 USA Swimming Championships, she won a gold and 2 bronze medals.

Hoff moved to Naples, Florida to train with T2 Aquatics under her former coach Paul Yetter, who had moved there from NBAC in 2010.

Hoff's plan for 2009 had been to train at Loyola College in Chicago, where it was reported she would entrole in classes and volunteer as an assistant swim coach, similar to what Michael Phelps had done at the University of Michigan. However, ESPN reported that she would instead remain at NBAC and switch coaches to work with Bob Bowman, who had announced in April 2008 that he was leaving Michigan's program after the Olympic trials. Bowman's coaching style did not mesh well with Hoff, and her time working with him ended in May 2009, when she came close to quitting the sport.

Hoff did not qualify for the 2009 World Aquatics Championships after an 8th-place finish in the 200-meter freestyle and a 6th-place finish in the 400-meter freestyle at the U.S. National Championships. Hoff subsequently withdrew from the 100- and 800-meter freestyle races, ending her chances of making the team.

Heading into the 2008 Olympics, Hoff was considered a strong contender. Hoff held the American record in the 200-meter individual medley at 2:09.71 and set the world record in the 400-meter individual medley with a time of 4:31.12 set at the 2008 U.S. swim trials. (This time was subsequently bettered by Stephanie Rice in the Olympic finals with a time of 4:29.45).

Hoff retained her 200-meter individual medley title by winning at the 2007 World Championships setting a new championship record of 2:10.13. Hoff's previous experience helped her use her "veteran" status to help the most experienced member of the U.S. team, Natalie Coughlin, prepare for their world-record-setting pace in the 4×200-meter freestyle relay.

At the 2005 World Aquatics Championships, Hoff set a championships record for her time of 2:10.41 in the women's 200 m individual medley. Hoff received two more gold medals at the competition, one in the 400-meter medley and the other for the 4×200-meter freestyle, with teammates Natalie Coughlin, Whitney Myers, and Kaitlin Sandeno.

Hoff qualified for the 2004 Summer Olympics at the age of 15; she failed to medal in both of the events in which she competed.

Hoff was born in Palo Alto, California and lived for a number of years in Williamsburg, Virginia, where she swam as a youngster with the Williamsburg Aquatic Club, coached by Harold Baker. She also swam summer neighborhood meets with the Windsor Forest Frogs, where several of her team records, circa 2000 and 2001 still stand. She moved with her family to Towson, Maryland in 2003, in part so she could practice with the North Baltimore Aquatic Club, also the home team of Michael Phelps. In 2008, she purchased a condominium in the Mount Washington neighborhood of Baltimore. Her mother, Jeanne Ruark Hoff, played basketball for Stanford University from 1979 to 1983. Hoff's father, John, is a salesman. Both Hoff and her younger brother, Christian, were home schooled. She is married to former Michigan State football player Todd Anderson. In December 2015, she announced her retirement from swimming.

Kathryn Elise Hoff (born June 3, 1989) is an American former competition swimmer, Olympic medalist, and former world record-holder. Though Hoff was known for her success in the 200- and 400-meter individual medley, she was a very capable swimmer in many events, ranging from the four 200-meter events to the 800-meter freestyle. She represented the United States at the 2004 Summer Olympics and 2008 Summer Olympics, in which she captured a silver and two bronze medals.
