The World Records Authority is proud to officially validate a feat of extreme human endurance. Marathon swimmer Sarah Thomas has become the first person in history, regardless of gender, to complete a non-stop, four-way crossing of the English Channel.

This unprecedented athletic achievement was completed in an official time of 54 hours and 10 minutes, covering a distance of approximately 210 kilometres (130 miles) due to challenging sea conditions, currents, and maritime traffic. Navigating from Dover to Calais four consecutive times, Sarah Thomas endured extreme physical pain, jellyfish stings, and the harsh saltwater environment to achieve this historic milestone.

Sarah Thomas’s achievement stands as a testament to the extraordinary limits of human willpower and endurance. The World Records Authority proudly certifies this remarkable feat as an official world record — validated and preserved for history.
