TV adventurer Ben Fogle is taking on his most punishing challenge yet - by swimming to Cornwall across the Atlantic Ocean.
With a target of 100 days to completion, the 38-year-old presenter will have to spend up to 12 hours a day in the water, swimming the equivalent of the Channel.
His 3,000-mile journey from the US will dwarf the gruelling achievement of comic David Walliams who swam much of the Thames last year.
No stranger to physical challenges, father-of-two Fogle has previously swum from San Francisco to Alcatraz and also competed in the notoriously difficult Marathon Des Sables.
In preparation, he will undergo a hard training schedule over the coming months ready to launch his Atlantic swim next year in 2013.
Accompanied by a support yacht on which he will sleep and refuel, Fogle will log his starting and stopping points each day to ensure he swims the full distance. This challenge has only been completed once before.
Swimming in aid of homeless charity Centrepoint , he will also give several young homeless volunteers the skills and opportunities to work on the project as both his short support team and yacht crew.
Scientists from the University of Southampton will also be able to track and research temperatures, currents and marine organisms due to sensors Fogle will carry on his body.
Keen to highlight the environmental factors of such an expedition, Fogle will work with the World Wide Fund for Nature (WWF) and the Plastic Oceans Foundation to use the trip to highlight the fragile state of the seas.
