An American woman has become the first person to ever swim across the English Channel four times without stopping.
Open water marathon swimmer Sarah Thomas completed the challenge on Monday morning after more than 54 hours of swimming.
While the swim was due to be 80 miles, the 37-year-old ended up swimming almost 134 miles due to strong currents, according to her tracker.
The feat comes just a year after Thomas completed treatment for an aggressive form of breast cancer, having been diagnosed in November 2017.
Ahead of the challenge, Thomas dedicated the swim “to all the survivors out there”.
“This is for those of you just starting your cancer journey and those of you who are thriving with cancer kicked firmly into the past, and for everyone in between,” she wrote on Facebook.
“I’m holding you all in my heart and swimming for our health and futures. We are stronger together, each and every one of us.”
Endurance swimmer Lewis Pugh called Thomas an “extraordinary, amazing, super-human”.
“Just when we think we’ve reached the limit of human endurance, someone shatters the records,” he wrote on Twitter.
“Huge congratulations to Sarah Thomas on swimming the English Channel 4x continuously!”
Speaking after the swim, Thomas told the BBC: “I just can’t believe we did it.”
“My crew was really great about helping me out and keeping me strong.”
“Every length had something that was really hard about it. Coming back from France the last time was definitely hard. It took forever and the current pushed me all over.
