Plan supporters take the Four Corners Challenge

Christine Godfrey and William Lewis have taken on an awesome challenge - an overland car journey which takes in the 'four corners' of the earth in one epic trip.

Christine writes: "We are setting out to drive around the Four Corners of the World, something never before attempted in one journey, and we're doing it to help raise the funds for the restoration of the primary school in Guatemala.

"They need three new class rooms, a new roof, a library and educational materials for the children.

"We're both in our 60s and we're setting off from the UK heading north to the top of Norway, going East into North Russia dropping down into Siberia and East to the Pacific via a dip down into Mongolia.

"The car will then be shipped to Anchorage and we'll drive from top to bottom of the Americas. Ship again to Australia, across the island continent, ship again to Cape Town and back up Africa and home."

They have been travelling since May 2007 and have persevered in the face of car trouble, border delays and every variety of weather imaginable, but have also experienced beautiful scenery and wildlife and had the chance to meet William's sponsored child, Yoselin, in Guatemala.
