Emma McKeon won 7 medals at the Tokyo Olympics, making her the first woman to earn 7 medals in swimming at a single Games.
## What happened?
She set an Olympic record to win the 50-meter freestyle in 23.81 seconds.
The Australian completed the sprint double after her victory in the 100.
## Why it matters for Emma McKeon
McKeon leaves Tokyo with four golds and three bronze, tying the record for most medals won by a woman at a single Games set by Soviet gymnast Maria Gorokhovskaya in 1952.
She became the most decorated Olympian in Australia's history with 11 career medals.
McKeon has eclipsed the record of nine that she shared for one day with swimming greats Ian Thorpe and Leisel Jones.
## What comes next?
The 27-year-old from Brisbane comes from a swimming family.
Her father, Ron, was a swimmer who runs a learn-to-swim center south of Sydney.
McKeon watched the Olympics as a youngster and grew up wanting to do the same thing.
And she did, winning four medals — one gold, two silvers and a bronze — in Rio five years ago.
McKeon's efforts on the last day at the Tokyo pool mirrored that of American star Caeleb Dressel.
They both won the 50 free and swam the butterfly leg on victorious relays.
McKeon touched in 23.81 seconds in the 50 free.
In the medley relay, the Aussies beat the two-time defending champion Americans.
"I feel like it has been a bit of a roller coaster getting a gold medal and trying to keep the emotions at bay," McKeon said.
"I've never really looked at the stats of medal counts," she said.
"It is an honor because I know I've worked so hard for it."
So McKeon's teammates are lucky to have her on the team.
"I don't know how she does it. I'm exhausted," said Kyle Chalmers, one of McKeon's teammates.
"To win one gold medal or an Olympic medal, it's very, very special."
McKeon's brother, David, was the first brother-sister duo since 1960 to swim for Australia at the Olympics.
The duo swam for Australia at the Olympics five years ago in Rio.
McKeon's victory in the 50-meter freestyle was a notable one.
She set an Olympic record in the event.
The Australian's time of 23.81 seconds was the fastest in the field.
McKeon's win in the medley relay was also impressive.
The Aussies beat the Americans with an Olympic-record time.
McKeon's efforts at the Tokyo Olympics will be remembered for a long time.
She made history with her 7 medals.
And she became the most decorated Olympian in Australia's history.
