The cancer survivor is now the first person in the world to cross the sea between the UK and France nonstop four times in a row which is called the English Channel.
Sarah Tomas, 37, began her historic swimming career early on Sunday and completed two rounds of the English Channel after swimming for 54 hours.
Swimmers swimming marathons in the open seas, which had just completed breast cancer treatment a year ago, have named this record as 'cancer survivors'.
The marathon's swimming distance is apparently 80 miles, but it was 130 miles due to a sea storm.
Sarah Thoms completed her swimming trip at six o'clock Tuesday morning.
After completing his swim on the British coast Dover, She said, "I don't believe in doing this."
'I feel my body listening. There were a lot of people on the beach who wished me well and I liked them, but I was surprised at myself. '
She said that I wanted to sleep all day now: 'I'm so tired now.'
World-renowned swimmer Louise Peo said in her tweet, "When we think that humans have touched the limits of their endurance, at the same time someone has broken the record."
Last year, Sarah Thoms was treated for breast cancer and her care team said she was 'swimming to deal with the effects of her treatment.'
As a seasoned swimmer, Sarah completed an event at sea in 2007. She swam in the English Channel from coast to coast in 2012 and again in 2016.
In the month of August 2017, she swam one hundred four and a half miles to Lake Champlain, on the border between Canada and the United States. But later she found out she had cancer.
Sarah Thomas completed breast cancer treatment in 2018 and is recovering and has made this record without swimming in her English Channel as a cancer survivor.
Sarah Thomas spent two rounds in 54 hours from the coast of Britain to the coast of France.
Normally, this distance should have been 80 miles, but because of the power of the high waves, she increased that distance by 60 percent, meaning she had to swim 130 miles in total.
Earlier there were only four swimmers who crossed the English Channel three times without stopping.
No one had crossed the line four times before Sarah Thoms. Britain's leading broadcaster and author Charlie Connelly commented on Sarah's achievement, saying, "This is one of the best works of physical and mental endurance in human history." Another observer Kevin Murphy said that Sarah had 'touched the end of the universe.'
Sarah said it was a difficult task to go against the tropical waves during swimming because it pushed them beyond their intended path. And then in the meantime they were even disinfected by a jellyfish.
But what was worse was the 'salty water of the sea, it hurts in the throat, in the mouth and on the tongue.' Sarah added, 'Each bar was a new challenge in its own style. 'The last trip from France back to Britain was the most difficult. It seemed to be an endless journey, and powerful waves were constantly pushing me around.
'A jellyfish pierced my face. The water was not as cold as I was concerned but still cold. '
Sarah also adhered to the 'Channel Swimming Association' rules while swimming in the English Channel, which meant that she could wear a swimming suit, a Google and a cap.
For their diet, Sarah used a protein-rich beverage, including electrolytes, and did not sleep due to caffeine. Her mother said, 'It was all tied to a rope and she was pointing after every thirty minutes and we would throw it at her.' After swimming, they celebrated stepping on dry land and joining the record box with their champagne and chocolate.
