Aaron Peirsol

In November 2015 it was announced that Peirsol would be inducted into the International Swimming Hall of Fame Class of 2016 alongside fellow Americans Dara Torres and coach Bob Bowman.

On February 2, 2011, at the age of twenty-seven, Peirsol announced that he was officially retiring from professional swimming. This ended months of speculation after Peirsol withdrew from his spots in both the 2010 FINA World Swimming Championships (25 m) in Dubai and the 2011 World Aquatics Championships in Shanghai. Peirsol said he contemplated retirement after the 2008 Summer Olympics. In 2010, he said he had no further goals and found it difficult to swim because he "ended up doing everything (he) set out to do." He added, "Things outside of the sport started to interest me." Peirsol said it was "poetic" that he ended his career at the same pool he trained in as a kid at the 2010 Pan Pacific Swimming Championships. Peirsol plans to go to graduate school at the University of Texas at Austin to study political science.

At the 2010 National Championships, Peirsol placed second in both the 100- and 200-meter backstroke. In the 100-meter backstroke, Peirsol placed second to David Plummer, who touched just 0.03 s ahead. For Peirsol, it was his first loss in the 100-meter backstroke at a national championships since he placed 4th at the 2000 U.S. Olympic Team Trials. In the 200-meter backstroke, Peirsol placed second to Ryan Lochte, who finished 0.70 s ahead.

At the 2010 Pan Pacific Swimming Championships in Irvine, California, Peirsol won gold in the 100-meter backstroke and the 4×100-meter medley relay. Peirsol's first gold came in the 100-meter backstroke. Initially, Peirsol did not qualify to swim in the medal-awarding final because only a maximum of two swimmers from one country could enter in the finals and David Plummer and Ryan Lochte owned the top two American spots. However, Lochte withdrew from the 100-meter backstroke and as a result, Peirsol advanced to the finals. Peirsol won the gold in a time of 53.31, breaking his own championship record set in 2006. Peirsol then competed in the 200-meter backstroke but did not qualify to swim in the medal-awarding final, with Lochte and Tyler Clary taking the top two American spots. In his final event, the 4×100-meter medley relay, Peirsol won gold along with compatriots Mark Gangloff, Michael Phelps, and Nathan Adrian. This would be the last race of his international career. When the competition was over, Peirsol said he put his swimming equipment in a locker and walked away.

At the 2009 National Championships, the selection meet for the 2009 World Aquatics Championships, Peirsol won individual titles in the 100- and 200-meter backstroke. In his first event, the 100-meter backstroke, Peirsol won in a time of 51.94, reclaiming the world record from Aschwin Wildeboer Faber. In winning the 100-meter backstroke, Peirsol became the first person to swim the event in under 52 seconds and it was the sixth time he set the world record in the event. In the 200-meter backstroke, Peirsol defeated Ryan Lochte and reclaimed the 200-meter backstroke world record he lost in Beijing. Peirsol also competed in the 100-meter butterfly but did not qualify for the event in Rome, finishing in third place.

At the 2009 World Aquatics Championships in Rome, Peirsol won two gold medals. In his first event, the 100-meter backstroke, Peirsol surprised many after he failed to make the final, which he attributed to a miscalculation of his own position in the semi-finals. Peirsol said, "I thought I was going faster. I am very disappointed. I completely misjudged my race. I have to go on, pick myself up and focus on my next events." But Peirsol's world record in the 100-meter backstroke would stay in place after the final. In his second event, the 200-meter backstroke, Peirsol won the gold in a time of 1:51.92, breaking his own world record of 1:53.08 by more than a second. Peirsol then competed in the 50-meter backstroke but did not advance past the heats. In his last event, the 4×100-meter medley relay, Peirsol combined with Eric Shanteau, Michael Phelps, and David Walters to win gold in a world record time of 3:27.28, lowering the old mark of 3:29.34 set a year ago in Beijing. While leading off the relay, Peirsol broke the championship record in the 100-meter backstroke with a time of 52.19, bettering the previous mark of 52.26 set by Junya Koga.

At the 2008 U.S. Olympic Team Trials, Peirsol won individual titles in the 100 and 200-meter backstroke, repeating his results from the 2004 U.S. Olympic Team Trials. In his first event, the 100-meter backstroke, Peirsol won ahead of Matt Grevers with a world record time of 52.89, lowering his previous mark of 52.98 set last year. In his second event, the 200-meter backstroke, Peirsol won in a time of 1:54.32, equalling Ryan Lochte's world record set last year. Lochte finished a close second, just 0.02 s behind Peirsol.

At the 2008 Summer Olympics in Beijing, China, Peirsol won gold in the 100-meter backstroke and the 4×100-meter medley relay. He also won silver in the 200-meter backstroke. In his first event, the 100-meter backstroke, Peirsol was the heavy favorite for gold, with him being the world-record holder and the defending Olympic champion. For the final of the 100-meter backstroke, Peirsol was swimming in lane two, having qualified fifth in the semi-finals. At the first 50-meters in the 100-meter backstroke final, Peirsol was in second place behind Liam Tancock, who took it out in 25.11. Peirsol was 0.54 s behind Tancock at the turn. However, after the turn, Peirsol overtook Tancock, who eventually placed sixth, and won the gold. Peirsol's final time of 52.54 was a new world record, bettering his previous mark of 52.89 set last month. After the race, Peirsol said, "I'm a little bit excited, a little bit relieved, absolutely elated." In his second event, the 200-meter backstroke, Peirsol placed second to Ryan Lochte 1:54.33 to 1:53.94. In winning the gold, Lochte broke the world record tie he and Peirsol shared in the 200-meter backstroke. In his last event, the 4×100-meter medley relay, Peirsol combined with Brendan Hansen, Michael Phelps, and Jason Lezak to win gold in a world record time of 3:29.34, lowering the old mark of 3:30.68 set four years ago in Athens.

At the 2007 World Aquatics Championships in Melbourne, Australia, Peirsol won one gold and one silver medal. In his first event, the 100-meter backstroke, Peirsol won gold in a world record time of 52.98, bettering his time of 53.17 set in 2005. Peirsol became the first man in the event to go under 53 seconds and beat Ryan Lochte by 0.52 s. At the time, Peirsol held five of the fastest times posted in the event. At one point during the first 50-meters, Peirsol was a full meter behind Ryan Lochte, and at the turn, Peirsol was in third place behind Liam Tancock and Lochte. But Peirsol had a superior finish to over-take both swimmers. After the race, Peirsol thanked Lochte for the fast start, which he attributed to the world record. In the 200-meter backstroke, Peirsol placed second to Lochte and lost his world record he set in 2006. Throughout the race, Peirsol was in first and at the 150-meter mark, Peirsol was ahead of Lochte 1:24.56 to 1:25.05. But Lochte had a strong finish to over-take Peirsol for the win. For Peirsol, it was his first international loss in the event since the 2000 Summer Olympics. Peirsol did not have a chance to swim in the 4×100-meter medley relay final because the United States was disqualified in the heats.

At the 2006 National Championships, the selection meet for the 2006 Pan Pacific Swimming Championships and the 2007 World Aquatics Championships, Peirsol won individual titles in the 100 and 200-meter backstroke. At the 2006 Pan Pacific Swimming Championships in Victoria, British Columbia, Peirsol won gold in the 100 and 200-meter backstroke and the 4×100-meter medley relay.

Peirsol was the only individual in the field to break 54 seconds and beat his closest competitor, Ryan Lochte, by 0.70 s. Peirsol earned his second gold in the 200-meter backstroke with a world record time of 1:54.44, bettering his previous mark of 1:54.66 set last year in Montreal. At the time, Peirsol held nine of the fastest times posted in the event and defeated second-place finisher Michael Phelps by 2.37 s.
