Phelps made his international debut at the 2000 Olympic Games in Australia, representing the United States. This marked the beginning of a stellar career that saw him become one of the most decorated athletes in Olympic history.

Achievements and Records

Phelps has accumulated numerous accolades throughout his career. He was honoured with a bust in the International Swimming Hall of Fame in 2014 and received a Lifetime Achievement Award from FINA in 2012. He has been named USA Swimming Male Swimmer of the Year eight times and World Swimming Magazine's World Swimmer of the Year seven times.

Olympic Success

At the 2004 Olympic Games, Phelps tied Mark Spitz's record by winning four gold medals in individual events. He also matched Soviet gymnast Alexandr Dityatin's record of eight medals at a single Olympic Games. In 2008, he surpassed expectations by winning eight gold medals, setting a new record for most golds at a single Olympics.

Retirement and Comeback

Phelps initially announced his retirement after the 2012 Olympic Games but left the door open for a return. He came back to competitive swimming in 2014 after an 18-month break. Following the 2016 Rio de Janeiro Olympics, where he won five gold medals, he retired again, stating he had nothing left to prove.

Personal Life and Interests

Phelps resides in Paradise Valley, Arizona, with his partner Nicole Johnson and their son Boomer, born in 2016. He enjoys music, supporting the Baltimore Ravens American football team, spending time with his bulldog Herman, and playing video games.

Challenges and Controversies

Phelps faced several challenges during his career. In October 2007, he broke a small bone in his wrist but returned to training within a month. He was banned for three months in 2009 after a photo of him smoking marijuana surfaced. In 2014, he was arrested for driving under the influence for the second time and received a six-month suspension from USA Swimming.

Future Plans

Looking ahead, Phelps plans to continue his involvement in swimming as a volunteer assistant coach at Arizona State University for the 2016/17 college season. His long-time coach Bob Bowman is now heading up Arizona State University's swim team.

Phelps' journey from a young swimmer following his sisters into the pool to becoming an Olympic legend is a testament to his dedication and talent. His legacy will continue to inspire future generations of swimmers worldwide.
