Calling themselves the Two Fat Yorkshiremen shows these guys have no illusions about their physical prowess.
But their lack of fitness has not deterred David Marsh and Nick Keating, from Balby, Doncaster, in their bid to reach the top of Mount Kilimanjaro in Africa.
At least they have more than two years to wean themselves off their unhealthy diet before they tackle the huge challenge for charity.
David and Nick, both aged 30, have been friends since school days at Balby Carr, but accept they have let themselves go a bit since they were running round the sports field.
It dawned on them as they struggled up England’s highest peak a few months ago during a weekend away.
David said: “We did it just for fun but at one stage I thought we might need a helicopter to get us off.
“But after we had a pork pie and a beer we felt better and decided it would be a good idea to try something more ambitious.
“Kilimanjaro is something I thought of doing for some time and I know it’s going to be a serious challenge.
“We thought we’d try and make a few quid for charity at the same time and three other friends have decided to join us.”
Climbing Africa’s highest mountain is not for the faint-hearted, especially when walking up a flight of stairs makes you breathless.
David and Nick have dubbed themselves the ‘Two Fat Yorkshiremen’ and have given themselves 24 months to get themselves to peak fitness and raise a staggering £40,000 for Macmillan Cancer Support.
David, a project designer for Portakabin, said: “I used to work on building sites but when I got this office job I was on my backside all day and I still enjoy a pint so soon got out of condition.
“I’m going to be cycling 60 miles to work to get fit and we’ll be doing the Three Peaks Walk in May as well as a lot more walking to get fitter.
“We want do this in aid of a good cause and I’m forever hearing about Macmillan‘s good work and almost everyone is touched by cancer at some point in their lives.”
The Two Fat Yorkshiremen will be joined by three friends, Mark McKay, Lee Madison and Josh Davis.
David, Nick and Mark have been life-long friends and Lee worked with David for a number of years, Josh is Nick’s future brother-in-law and they aim to raise £8,000 each.
Nick said: “The team are paying for their own travel and our main focus is to raise the money for Macmillan Cancer Support.
“We hope that businesses can get behind us and help us reach our goal. This might be through sponsorship of raffle prizes. We have some great ideas of how to give our sponsors the recognition they deserve.”
