In September 2019, marathon swimmer Sarah Thomas did something that had never been done before: she swam the English Channel four times, non-stop. And she did this a year after completing treatment for stage II breast cancer.

Sarah started swimming lessons at age one and was on a year-round swim team by age 10. She swam on her high school team and in College at the University of Connecticut where she studied political science and journalism. She took a break from swimming while earning a master’s degree at the University of Denver, but joined a masters’ swim team after graduating.

In August 2017, Sarah swam 104.6 miles in Lake Champlain, the first current-neutral open water swim of more than 100 miles and the world record for the longest unassisted open water swim.

In November 2017, while planning her English Channel swim, she was diagnosed with breast cancer at age 35.
