Adventurer James Ketchell and Scout Leader Ash Wilson, who suffers from Epilepsy, are aiming to break the record for rowing across the Indian Ocean.
They came to the Docklands to launch their boat for the very first time - I joined them in their boat for The Scout Association.
To give a sense of the challenge ahead of them - More people have been in space than have rowed across the Indian Ocean! Coupled with that, Ash's Epilepsy provides additional problems, worries and training needs for the pair.
The world record for a two-man crew to row across is 80 days, and 'the journey alone is the real achievement and goal, but if we can do it and get the record, that would be something amazing'.
The pair hope to inspire young people around the world that no matter what disability or challenges they face in life, nothing's impossible.
