A group of four adventurers in their seventies will take on a six month, over 27000km journey around the world behind the wheel of two Suzuki Jimny's as part of a charity drive - The Ultimate Challenge.In August 2013, the group completed their journey. Leslie Carvall and his team reached North Bergen on the eastern seaboard of the USA after a 27358km global drive which began in Southampton, southern England, in March 2013.Video: Les Carvall speaks on The Ultimate ChallengeThe 4x4s are now loaded to cross the Atlantic and will reach Southampton later in September 2013.The team of retired Suzuki Jimny fans drove around the planet on a fund-raising tour for the charity heavencanwait in aid of Save the Children and the Oakhaven Hospice in Lymington, Hampshire.16 COUNTRIES, THREE CONTINENTS...The project was masterminded by retired businessman Carvall and the trip was undertaken without any support crews. They drove alone for 150 days with no frills or luxuries.Carvall commented: “We wanted 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.”The Jimny, the team said, was chosen to prove the expedition could be achieved in inexpensive 4x4s "with a strong record of durability".Travelling through Canada and the US, they reported, was far easier than the very long and gruelling sections in May 2013 through Russia and Mongolia. The only failure was a broken shock-absorber bolt.The team’s progress through 16 countries and across three continents has been regularly updated on their website along with some interviews and humorous video clips taken during the five-month journey. As with any charity project, all donations would be gratefully accepted via their Just Giving website.
