St Katharine Docks will host the closing ceremony of the Thames paddleboard challenge.

Carlos De Sousa and Carolyn Newton from The Whale Company will take on the challenge aimed at raising awareness of plastic pollution in the waterways.

The pair embarked on their 17-day challenge earlier this month and will complete the 300 km trip on June 29.

Along the way, they have collected messages from school children in their ‘message in a bottle’ campaign and will deliver these directly to the government toward the end of their challenge.

Ms Newton said: “We aim to inspire people to rebuild connections with nature and cherish the world around us. Clearly, plastic pollution in our waterways has become such a threat that we are in danger of irreversibly damaging the purity of our rivers and seas.

“We are undertaking this challenge to demonstrate that paddle boarding and water sports are a brilliant way for everyone to get out on the water and reconnect with nature, whilst galvanising the support of the entire community to influence decision-makers and push this issue even further up the agenda.”

After travelling through Richmond, the pair will paddle to Kew Bridge in a sunset paddle. The closing ceremony will be at St Katharine Docks on June 29 at 5 pm, to celebrate the completion of their challenge and spread their message.
