A survivor of breast cancer, the American Sarah Thomas has crossed the Channel four times in a row, a first so far.

An American woman, a breast cancer survivor, became Tuesday the first person to swim across the English Channel four times in a row, a 54-hour performance. Sarah Thomas, 37, arrived Tuesday morning in Dover, southern England, to the applause of a small group of people. "I feel a little sick," we hear on a video posted on Facebook.

The swimmer made two round trips between Dover and Cap Gris-Nez, near Boulogne-sur-Mer, in the Pas-de-Calais region of France. Before starting this sporting adventure, Sarah Thomas also wrote on Saturday: "This swim is dedicated to all survivors, it is for those of us who have prayed for our lives, who have wondered in desperation what was going to happen, who fought, in pain and fear, to win. "

Stung by a jellyfish

Sarah Thomas's cancer treatment was completed a year ago. She told the BBC that the hardest part of the trip was the salt water, which burned her throat. She was also stung in the face by a jellyfish. Endurance swimmer Lewis Pugh praised Twitter for an "extraordinary, brilliant and superhuman" performance.
