DETERMINED Hounslow residents are to travel a third of the earth's surface in a Micra with a 1 litre engine.
Hassan Ibrahim from Feltham, and Hounslow resident Paul D'Silva will be joined by friend Ambrish Patel, of Gravesend, at this year's Mongol Rally.
The challenge will see the team travel 10,000 miles in the eight-year-old Nissan over three deserts and five mountain ranges.
Mr Ibrahim, a civil servant of Chertsey Road, said: "Me and Paul work together for the home office. It was actually his idea, he tried to enter it last year and basically they ran out of places.
"He asked if I was interested, I kind of just said yes I would do it but it kind of didn't register at the time. It is obviously something a bit different and not something you get the chance to do all the time."
The lads hope to raise £4,000 for four different charities, the Christina Noble Children Foundation, the CYPPD, the Mercy Corps and SANDS.
They are funding the entire cost of the trip from their own pockets so every penny donated will go to charity.
The route, which goes from London to Mongolia, will see the team travel through France, Belgium, Germany, Romania, Iran, and Russia among other places. They will sleep where they can along the way.
Mr Ibrahim said: "We don't know exactly how much it will cost yet or how long it will take. I am sure we will be held up at borders, we will probably break down in the middle of the desert, but we hope it will take about five weeks. I am really looking forward to it, I think it is one of these once in a lifetime things. It is a very remote chance actually being given the opportunity."
