Emma McKeon won two more gold medals at the Tokyo Olympics on Sunday, making the Australian the first woman to earn seven medals in swimming at a single game.

She set an Olympic record to win the 50-meter freestyle in 23.81 seconds, completing the sprint double after her victory in the 100.

Thirty minutes later, McKeon dived back in the pool to win again, this time as part of Australia’s 4×100 medley relay. They trailed the Americans after her butterfly leg, but anchor Cate Campbell sprinted past Abbey Weitzeil to clinch the victory with an Olympic-record time.

“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. “It will take a while to sink in because I’ve been focusing on myself to keep my cool.”

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 in Helsinki.
