British Olympian swims the largest lakes in England, Wales, and Scotland in under 24 hours in campaign against water pollution

Britain's Hector Pardoe swims in the Seine river during the men's 10km marathon swimming final at the Paris 2024 Olympic Games at Pont Alexandre III in Paris on August 9, 2024.

An Olympic open water swimmer has become the first person to swim across the largest lakes in England, Wales, and Scotland in under 24 hours, to raise money and awareness for the ongoing pollution crisis in British waters.

Hector Pardoe, 24, swam the lengths of Lake Windermere, Lake Bala, and Loch Lomond, to complete a total distance of 34 miles (55km) in an effort inspired by the popular three peaks hiking challenge.
