Olympic open water swimmer Hector Pardoe has launched a campaign advocating for cleaner rivers and lakes, drawing attention to pollution that has affected both his health and that of fellow athletes. Pardoe’s push for improved water quality follows his extensive encounters with polluted waterways during training and competition.

In August 2025, Pardoe completed a historic swim across Britain’s three largest lakes—Windermere, Loch Lomond, and Bala Lake—covering a combined distance of 55 kilometers in under 24 hours. This unprecedented effort aimed to raise funds for the environmental charity Surfers Against Sewage, while spotlighting the increasing threat of pollution in natural water bodies essential to open water swimming.

The athlete has urged water companies to take greater responsibility for sewage discharges, emphasizing the impact of pollution on public health and sporting environments. Pardoe’s advocacy has gained traction alongside his continued success in competitive swimming.

He earned a bronze medal at the 2024 World Aquatics Championships and secured sixth place in the 10km marathon swim at the Paris Olympics in 2024. Recognizing his contributions beyond the pool, Pardoe was named Athlete of the Year at the 2025 BBC Green Sport Awards.

By leveraging his high-profile athletic career, Pardoe aims to raise awareness about environmental issues facing waterways and to encourage policies that hold polluters accountable. His campaign exemplifies how elite athletes can use their platforms to advocate for broader social and environmental causes alongside their sporting achievements.
