LONDON, England - A group of four adventurers in their seventies will take on a six month, 45061km journey around the world behind the wheel of two Suzuki Jimny's as part of a charity drive - The Ultimate Challenge.The Ultimate Challenge is the brainchild of Les Carvall, a reluctant retiree from Lymington, UK. Whilst on holiday, Les thought up a project to keep him active and was inspired by seeing a convoy of cars participating in the Paris – Peking Rally. 'AGE IS NO BARRIER'After two years of planning, the Ultimate Challenge team made up of Les and three friends (with a combined age of 297) will leave the UK on the March 31 2013.Their journey will take them through sixteen countries, three continents and across two major oceans. The journey will take approximately six months and 45061km to complete.Les commented: “We want to undertake this challenge to show that age is no barrier to getting up and getting on with living life and giving something back to society while we still have time.”Preparation for the journey has included the selection and modification of two Suzuki Jimnys. Minor modifications include heavy duty front and rear bumpers, suspension modifications, all terrain tyres with steel rims and luggage racks.The Ultimate Challenge team has been instructed on vehicle maintenance and repair from Newmans Suzuki at Totton, Southampton who are one of the sponsors. The group has been through physical training to cope with the variety of conditions they will encounter during the journey.The Charity "Heaven Can Wait I’m Busy" was formed and the Ultimate Challenge is to be the first major activity planned to raise money for the Save the Children, Oakhaven Hospice in Lymington, UK and other worthy causes.Along the way, the team will be producing a film documenting their progress which will be titled “While We Have Time”. All proceeds from the film will be donated to Save the Children.
