Indesit is sponsoring its national account manager Adam Walker to swim 26 miles down Hawaii’s Molokai Straits to raise money for Sportsaid.

Adam has already swum the English Channel and the Gibraltar Straits, but said the Hawaii swim would be the hardest yet.

“This swim should take around 13 to 14 hours and will be the hardest challenge of my life. I will be up against huge swells and aggressive marine life, like whales, jellyfish and, of course, tiger sharks.”

The swim will bring Mr Walker one step closer to completing the Ocean 7 Challenge, to conquer the seven hardest swims in the world.

The remaining swims are the Catalina Channel (from Santa Catalina island to California), the Cook Strait (between the north and south islands of New Zealand), the Tsugara Channel (between the islands of Honshu and Hokkaido in northern Japan) and the North Channel (Ireland to Scotland).

Mr Walker is using his latest swim to raise money for Sportsaid, a charity helping young British sportspeople achieve their sporting ambitions. Donations can be made to www.justgiving.com/molokaistraitswim.
