A man with cerebral palsy is preparing to single-handedly row 3,000 miles across the Atlantic Ocean for charity.
Stuart Boreham is expecting to be at sea for 80-90 days, with no more than his lucky mascot - a teddy bear - to keep him company.
The 37-year-old will depart from La Gomera, in the Canary Islands on Saturday.
He will reach land again at Barbados in the Caribbean, where he plans to take a break following 18 months preparation for the gruelling trip.
If he succeeds Mr Boreham, from Stornoway in the Outer Hebrides, will be the first physically disabled rower to achieve the feat.
The clerical medical investment manager has had several operations on his legs and feet to improve his ability to walk, since being diagnosed with cerebral palsy as a child.
He hopes to raise at least £25,000 from the event, for Macmillan Cancer Relief, to fund a nurse for a year.
His 24 foot long purpose-built rowing boat is called 'Macmillan spirit'.
Mr Boreham was inspired to take on the challenge after doing the 1996/97 BT global challenge round the world yacht race.
"I was able to help to generate a momentum to show both able-bodied and disabled people alike that having a disability didn't mean you couldn't achieve something in your life."
He chose the challenge when he realised no one with a physical disability had ever rowed an ocean before.
His progress will be followed by a BBC documentary team and updates will be posted on his website at to www.teambluemarble.com
