Sarah Thomas

Sarah Thomas (born 1982) is an American marathon swimmer.

On August 10, 2017 she swam 104.6 miles (168.3 km) in Lake Champlain, the first current-neutral open water swim of over 100 miles, and as of 2019 the world record for longest unassisted open-water swim. Her route was a loop starting and finishing at Rouses Point, New York at the north of the lake and swimming south to and around Gardiner Island, Addison County, Vermont.

In November 2017 she was diagnosed with breast cancer, and underwent surgery, radiotherapy and chemotherapy, swimming as much as possible during her treatment.

On September 17, 2019 she became the first swimmer to swim four consecutive crossings of the English Channel, in a time of 54 hours 10 minutes. A documentary film about this swim, The Other Side, is being made, funded through Kickstarter.

Thomas was swimming in a year-round swimming team by the age of ten. She swam in high school at the 200m and 500m freestyle, and in the mile in her senior year. She continued swimming while studying for a degree in political science and journalism at the University of Connecticut, but gave it up while gaining her Masters in legal administration at the University of Denver. She took up swimming again and joined a masters swim team after graduating.

In August 2007 Thomas made her first long swim, the annual 10 km Horsetooth Open Water Swim at Horsetooth Reservoir, near Fort Collins, Colorado, over 5,400 feet (1,600 m) above sea level. She was the second woman completer, and the fifth overall, in 2 hrs 39 mins 8 sec. She has said "I got out of the water, and I was fighting back tears because I loved it so much."

She works as a recruiter for a health care company, and lives in Conifer, Colorado with her husband.
