A husband and wife will swim a kilometre in the freezing cold waters of the Arctic Circle and Antarctica to raise money for Weston Hospicecare.

Doctors Adam Baker and Charlie Fleury, who love a challenge for a worthy cause, already have a history of intense experiences.

They previously completed a 3,000-mile row across the Atlantic and a 1683-mile partial circumnavigation row around Britain.

Now, they are taking on the daunting Archipelago Yachts Polar Swim challenge.

The challenge will see the couple swimming a kilometre in the freezing waters of the Arctic Circle and Antarctica.

Dressed only in conventional swimsuits and caps, the pair will face water temperatures between -1°C and 4°C.

Only 12 people have achieved this so far, given the dangers of cold-water shock, hypothermia and predatory wildlife such as orcas, leopard seals, and polar bears.

Adam Baker, a palliative care doctor at Weston Hospicecare, said: "I’m passionate about helping people overcome the enormous challenges they may face, and I am immensely proud to be part of the team here at Weston Hospicecare which does such an exceptional job supporting people with life-limiting conditions and their families across North Somerset and Somerset."

This explains why Weston Hospicecare is one of the couple's chosen charities.

They also plan to raise funds for the Ocean Conservation Trust, aiming to raise a total of £20,000.

The challenge will start in September, with the first swim in the Arctic Circle just off Svalbard, Norway.

The second swim will be held in Antarctica in November.

The couple will tackle the harshest environments on the planet, but they need public support.

Ms Fleury said: "Reaching our fundraising target for our amazing charities would be incredible.

"We would be delighted if people would help by donating via our website."

Weston Hospicecare was established in 1989 by members of the Weston-super-Mare community, who recognised the need for end-of-life care.

Since then, the hospice has grown and currently supports over 1,000 patients and their families every year thanks to generous charitable gifts like this upcoming swimming challenge from Mr Baker and Ms Fleury.
