Between 15-26 May 2025, Lewis Pugh will swim around the island of Martha’s Vineyard, to highlight the perilous plight of sharks around the world.

Follow Lewis live as he becomes the first person to swim the 60 mile (96 km) circumference of Martha’s Vineyard, Cape Cod.

In August 2023, Lewis Pugh swam 315 miles (507 km) down the Hudson River, from its source to its end at the Atlantic Ocean. He did this to highlight the critical role rivers play in a habitable planet, emphasising the interconnectedness of rivers and oceans, and stressing the urgent need to protect and respect them.

“If we want healthy oceans we also need healthy rivers — it’s that simple.”

The 123 km swim took 16 days to complete.

In October 2022, Lewis competed the frist swim across the Red Sea, from Saudi Arabia to Hurghada, Egypt. Along the way he passed Sharm el-Sheikh, where world leaders would gather for COP27 in November.

The 123 km swim took 16 days to complete.

On September 7, 2021, Lewis became the first person to complete a multi-day swim in the Polar Regions, when he swam across Greenland's Ilulissat Icefjord, fed by the world’s fastest moving glacier.

In 2020 Lewis completed the world's first swim under the Antarctic Ice sheet, to highlight surface melting that is more widespread than previously thought.

The Long Swim marked the beginning of a worldwide campaign to ensure that 30% of our oceans are fully protected by 2030.

South Georgia and the South Sandwich Islands (SGSSI) are the most important wildlife haven under British jurisdiction – yet when Lewis swam there in November 2017 only 2% of this biodiversity hotspot was fully protected.

Ten years after his pioneering swim across the North Pole, Lewis Pugh returned to the Arctic to see for himself how the area had weathered a decade of global warming. What he found was alarming.

Our Antarctica 2020 campaign was timed to commemorate the 200-year anniversary of Antarctica's discovery with a chain of Marine Protected Areas around the continent.

For five years, CCAMLR (Convention for the Conservation of Antarctic Marine Living Resources), the body that oversees the protection of Antarctic waters, struggled to create a Marine Protected Area in the fragile Ross Sea.

In 2007 Lewis Pugh attempted the impossible: to swim across the North Pole without any protection other than a pair of speedo swimming trunks.

‍In 2016 Afroz Shah invited Lewis join the collective of volunteers gathering in Mumbai every weekend, each of them donating hours of their time to participate what has become the world's biggest beach clean up.

The African penguin is likely to be functionally extinct on South Africa’s west coast in less than 15 years, unless we take immediate action.

In 2016 we helped negotiate the halt to an annual mass balloon release in Gibraltar that had been practiced for 24 years.
