Mr Scott (53) has run the 26.2-mile race twice, in 1992 and 1996.
Since then he has undergone major surgery when he had a kidney transplant operation almost three years ago.
But now he wants to run the London again in 2008 and will be trying to recruit 42 others who have never competed in a marathon before divided into seven teams, each led by runners who have had marathon experience.
The objective is to raise £100,000 for a local children’s charity in conjunction with the Variety Club, who are allocated a number of marathon entries each year.
HSBC Investments have already agreed to sponsor the project.
Mr Scott said: ‘How many people do you hear say “”I wish I could do that”” when they see the London Marathon on television? My plan is to give them the chance – I believe all they want is for someone to give them the opportunity as part of a team.
It doesn’t matter if they’ve never run before.
‘It’s difficult to express the feelings you go through during the race, but they are immense.
After ten months of training just to be there and experience the occasion is wonderful.
It’s an unforgettable day in anyone’s life – it really is life-changing.
Doing something like this gives people confidence they might never have had before and often they make friends for life along the way.’
